The correct answer is 0.5. We'll presume you're converting moles of 2.00 to grams. The mole is the SI base unit for substance quantity. 1 mole is 2 grams or 1 mole 2.00. It should be noted that rounding mistakes might occur, therefore always double-check the findings. Learn how to convert between moles of 2.00 and grams with this website.
More information about each measuring unit may be found here: The mole is the SI base unit for substance quantity. 1 mole is equivalent to 488.02891 grams or 1 mole 7 AmU.
The amu is the unit of mass in the American system of units. It is equal to 1/7th of a gram, or 0.14 grams. The term "amu" comes from the first three letters of the words "American system". The Japanese use the kibiwo (or kilibo) which is equivalent to the kilogram.
Even though the amu and the mole are both used to measure elemental weight, they represent different concepts. The mole is based on the molecular weight of carbon 12 while the amu is based on the atomic weight of carbon 12. Thus, one mole of carbon 12 contains exactly 6.02E23 atoms, while one amu of carbon 12 contains 70.8 atoms.
It is important to note that there are other elements besides carbon that can be used to create molecules or atoms. For example, one mole of oxygen 16 contains 32 grams, while one amu of oxygen 16 contains 205.7595 grams. Oxygen is the most common element used to create molecules, and thus, it makes sense that one mole of oxygen contains more than one amu.
A gram of lead equals 0.0048262548262548 moles. Multiply this number by 1,000 to obtain the mass in milligrams of lead.
One gram of uranium is 0.0042011703536348 moles. A mole contains 6.02214179202544 x 1023 molecules.
Uranium has a density of about 5.5 grams per cubic centimeter. So, one gram of uranium weighs about 0.055 milligrams. The number of moles can be calculated by dividing the weight by the density: 0.055 mg/cm3 = 55,000 moles / 100 g / 3.99 g/mol. There are about 7 million atoms of uranium in one gram!
On average, each atom of uranium is made up of 92 protons and neutrons. This gives uranium its atomic mass value of 238.0669701. It is the heaviest element that occurs naturally on Earth. Only artificial elements make heavier than uranium have been created in laboratories. Uranium is present in almost all rocks as the most abundant metal after iron. It is also found in some minerals such as uraninite or moonstone. Some uranium is also found in seawater at concentrations about 1 part in 270,000.
Uranium was first discovered by J. H. Lawrence in 1892.
One mole of a material represents 6.022 x 1023 individuals. One mole of an element comprises 6.022 x 1023 of the element's atoms. One mole of a material equals one gram of the substance's formula mass. Because one mole of carbon 12 has a mass of 12 grams, one mole of carbon is very important in chemistry.
Class 9 molecules are large and complex. The largest molecule found in nature is DNA, which is a class 9 molecule used to store genetic information in cells. A typical molecule for a class 9 compound must contain at least 39 elements. These elements may be different isotopes of the same element (as with nitrogen 14N and 15N), or they may be different elements (as with fluorine 18F). Some molecules contain dozens of elements; others contain only two or three elements. There are no restrictions on the number of atoms you can have as long as your molecule stays within the confines of class 9.
Molecules are made up of atoms which are the smallest part of a chemical element. Molecules are formed when several atoms unite together. The force responsible for holding atoms together is called "covalent bonding". In covalent bonds, electrons from all the atoms involved share their outer shells with each other. This leaves little room for any other electron clouds to interfere with the bonding process. Covalent bonding is also what keeps atoms together to form molecules.
It's just a handy unit to have on hand while doing computations. When you initially learn how to use it, you may find it inconvenient, but after you get the hang of it, a mole will be as common as a dozen or a byte.

Copper (I) sulfide is another name for this chemical. 1 gram of Cu2S = 0.0062831041047519 moles. Learn how to convert grams of Cu2S to moles on this website.
A mole is the amount of substance that contains as many molecules as there are atoms in a single molecule of carbon 12 (C12H24). Because each atom of carbon 12 has six electrons in its outer shell, and because atoms need to have an even number of electrons in order to be stable, it can be concluded that a single molecule of C12H24 is sufficient to contain all the electrons needed for stability.
In terms of mass, a mole is equal to the weight of 12 grams of carbon-12. One mole contains 6.022×1023 molecules. A mole of Cu2S weighs in at about 80.37 grams. That's a lot of copper!
Cu2S is used in certain materials used in solar cells, where it helps reduce cost while maintaining good performance. A film of Cu2S acts as an electron collector's plate, allowing less expensive materials to be used in solar cell construction.
Solar cells use the energy from sunlight to produce electricity. They do so by using silicon semiconductors to split water into oxygen and hydrogen gas.
