#### Answer

a) $835\ g$ b) $62.4\ g$ c) $12\ g$ d) $0.886\ g$

#### Work Step by Step

Atomic weights: $Au: 196.97u,\ He: 4.0026u,\ Pt: 195.08u,\ Pu: 244u$ a) $4.24\ mol \times 196.97\ g/mol = 835\ g$ b) $15.6\ mol \times 4.0026\ g/mol = 62.4\ g$ c) $0.063\ mol \times 195.08\ g/mol = 12\ g$ d) $3.63\times10^{-4}\ mol \times 244\ g/mol = 0.886\ g$
