A mole is the amount of a substance equal to the standard atomic weight (or combined atomic masses of all atoms in each molecule of a compound). To find out the mass, you look up the atomic weight and multiply by the number of moles (or add weights for the atoms of a covalent compound; it's a little more complicated for ionic compounds). Copper has an atomic weight of approx. 63.546 g/mol, so 0.9 mol of copper has a mass of (63.546 g/mol)(0.9 mol) ~ 57 g. Also, assuming your measurement has an uncertainty of 0.05 mol (the usual convention), the uncertainty for the 57 g would be approx. (63.546 g/mol)(0.05 mol) ~ 3 g. (That's not quite the correct formula for the total uncertainty, but it's a reasonable approximation in this case.) (Atomic weights: http://media.iupac.org/publications/pac/2006/pdf/7811x2051.pdf )

Copper is a transition element used in the making of coins calculate the mass in grams of 0.0420 moles of copper?
To calculate the mass of copper in grams, you first need to find the molar mass of copper, which is approximately 63.55 g/mol. Then, multiply the number of moles (0.0420 moles) by the molar mass to get the mass in grams. Mass = moles x molar mass Mass = 0.0420 moles x 63.55 g/mol = 2.67 grams of copper.

What is the mass of copper if it contains same number of atoms as present in 3.2 grams of sulphur?
To find the mass of copper containing the same number of atoms as in 3.2 grams of sulfur, we first determine the number of moles of sulfur. Sulfur has a molar mass of approximately 32 g/mol, so 3.2 grams corresponds to 0.1 moles of sulfur. Since copper (Cu) has a molar mass of about 63.5 g/mol, the mass of copper that has the same number of moles (0.1 moles) is calculated as 0.1 moles × 63.5 g/mol = 6.35 grams. Therefore, the mass of copper is 6.35 grams.
