A chemist requires 0.780 mol Na2CO3 for a reaction. How many grams does this correspond to?

just get the molar mass and use multiplication by one, meaning it would be mol/1 x grams(from molar mass)/moles(1)of the compound.
I think it is easier this way.
grams = mols x molar mass.
grams = mols x molar mass.
