To find the mass of 0.125 moles of copper (II) oxide (CuO), you need to determine the molar mass of CuO which is 79.55 g/mol. Multiply the molar mass by the number of moles to get the mass. Therefore, 0.125 moles of CuO would have a mass of 9.94 grams.
Remember the equation. Moles = mass(g) / Ar So for Copper. 1 mole = mass(g) / 63.5 (Atomic mass from Periodic Table) Algebraically rearrgange mass(g) = 1 mole X 63.5 Mass = 63.5 g per mole.
The molar mass of copper is 63.55 grams per mole.
Atomic mass of Cu is 63.55 a.m.u. , 63.55 g/mole(Cu is an element, not a molecule)
It isn't. The mass of one mole of aluminum is less than the mass of one mole of copper. The number of atoms in one mole of aluminum is the same as the number of atoms in one mole of copper, which is 6.022 x 1023, also known as Avogodro's number.
No, the molar mass of copper is approximately 63.55 grams per mole. Therefore, the mass of 0.50 moles of copper would be 0.50 moles x 63.55 g/mol = 31.77 grams.

A mole of any substance contains Avogadro's number of particles (6.02 x 10^23). The molar mass of copper is less than that of lead, so a mole of copper atoms weighs less than a mole of lead atoms, despite both containing the same number of atoms.
To calculate the mass of 19 atoms of copper in grams, you need to determine the molar mass of copper. The molar mass of copper is approximately 63.55 grams per mole. Then, you can use Avogadro's number (6.022 x 10^23 atoms per mole) to convert atoms to grams. So, the mass of 19 atoms of copper would be 19*(63.55/6.022e23) grams.
The periodic table states that the molar mass of copper is 63.546 grams per mole. That means that if you have one mole of copper, it will weigh 63.546 grams. One mole is 6.022x1023 (Avogadro's number) atoms. To find the mass of one copper atom in grams, you simply divide copper's molar mass by the number of atoms in one mole. 63.546 / 6.022x1023 = 1.055x10-22 One atom of copper weighs 1.055x10-22 grams.
The lowest whole number mass ratio of copper that combines with a given mass of chlorine is 1:1, meaning each mole of copper combines with one mole of chlorine. This corresponds to the compound copper (I) chloride, where the mass ratio would be 63.5 grams of copper to 35.5 grams of chlorine.
Weight of one mole of CuBr=molecular weight of CuBr=(63.545+79.904)=143.449 g. So, weight of 0.500 mole of CuBr=(143.449 X 0.500)g=71.725 g.
The mass of a single copper atom is approximately 1.055 x 10^-25 kilograms. This value is determined by the atomic mass of copper (63.55 grams per mole) and Avogadro's number.
The mass of a molecule of copper oxide is the sum of the atomic masses of copper (Cu) and oxygen (O) in the molecule. The molecular formula of copper oxide is CuO, so the mass would be the atomic mass of Cu (63.55 g/mol) plus the atomic mass of O (16.00 g/mol), which equals 79.55 g/mol.
