Best answer: How many moles are in 1 gram of zinc?

How do you find moles from 1 gram?

Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass.

How many moles are in 3.55 g of Zn?

We have three significant figures here. So we’re gonna say point 295 moles. We can do the same thing with 3.55 g of zinc. The molar mass of zinc is different.

How many moles are in 1 gram of MG?

For example, one atom of magnesium weighs 24.31 amu (atomic mass units). However, one mole of magnesium weighs 24.31 g. (Moles were planned that way!)

What is the formula for calculating moles?
