Answer
(a) 0.034 g
(b) 0.31 g
(c) 0.43 g
Work Step by Step
(a) Molar mass (Sodium) = 22.99 g/mol
$0.0015 mol \times \frac{22.99g}{1mol} = 0.034$ g
(b) Molar mass (Lead) = 207.2 g/mol
$0.0015 mol \times \frac{207.2g}{1mol} = 0.31$ g
(c) Molar Mass ($C_{16}H_{13}ClN_2O$):
12.01* 16 + 1.008* 13 + 35.45* 1 + 14.01* 2 + 16.00* 1 = 284.7 g/mol
$0.0015 mol \times \frac{284.7g}{1mol} = 0.43$ g
