1 mol of an element is equal to it's atomic weight, but with grams instead of amu (or daltons) as the unit.
For example, with copper (Cu), 63.5 amu is its rough atomic weight, which means it weighs roughly 63.5g per mol.
Then we just need to divide through.
63.5 x 0.345 = 21.9g

∙ 15y agoFor this you need the Atomic Mass of Cu. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.
3.5 moles Cu × 63.5 grams = .0551 grams Cu

∙ 14y agoFor every 1 mol of Cu, it has 63.55 grams.
Therefore, using stoichiometry to cancel out the moles, you'd multiply 7.70 mols of Cu to 63.55 grams.
About 489 grams of Cu.

How many moles in NaCHO3?
A mole is a defined number of atoms/molecules of an element/compound. Therefore, the number of moles of NaCHO3 will depend on the mass of NaCHO3 that you have. To calculate the number of moles in a known sample, divide the mass of the sample (in grams) by the molecular weight.
