How do you convert 5.2 moles of lead to grams?

Answer 1

Using the formula number of moles = mass divided by molar mass

so mass = number of moles X molar mass

Find molar mass by adding up the masses of all the atoms in your substance.


A good way to remember this is as the formula g/mw = moles, and the mnemonic for this is


"Mine workers (mw= molecular weight) under ground (grams of compound you are dealing


with = Moles!

Answer 2

For this you need the Atomic Mass of Pb. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.

5.2 moles Pb × (207.2 grams) = 1077.44 grams Pb
