Molar mass of Pb = 207.2 g/mol
Mass of the Pb = (17.00 mol) × (207.2 g/mol) = 3522 g
Volume of the Pb = (3522 g) / (11.34 g/cm³) = 310.6 cm³
====
OR:
(17.00 mol Pb) × (207.2 g Pb / 1 mol Pb) × (1 cm³ Pb / 11.34 g Pb)
= 310.6 cm³ Pb
Mass of the Pb = (17.00 mol) × (207.2 g/mol) = 3522 g
Volume of the Pb = (3522 g) / (11.34 g/cm³) = 310.6 cm³
