Use the Equation
Moles = mass(g) / Mr (Relative molecular mass).
Algebraically rearrange
mass(g) = Moles X Mr
We have
4 moles
Mr(HNO3) is
From the atomic masses in the Periodi Table
1 x H = 1 x 1 = 1
1 x N = 1 x 14 = 14
3 x O = 3 x 16 = 48
1 + 14 + 48 = 63
Substitute in
mass(g) = 4 x 63
mass(HNO3) = 252 grams.
NB Bearing in mind that nitric acid is usually dissolved in water , the mass of 4 moles will be greater than 252 grams, in order to account for the mass of solvent(water).
