Answer 1

1) $CO (g) + 2H_{2}(g) ---> CH_{3}OH (g)$

Moles of methanol = $208 kg CH_{3}OH * \frac{1000 g}{1 kg} * \frac{1 mol CH_{3}OH}{32.04 g CH_{3}OH} = 6492 mol CH_{3}OH$

Mass of $H_{2}$ that would produce 208 kg methanol =

$6492 mol CH_{3}OH * \frac{2 mol H_{2}}{1 mol CH_{3}OH} * \frac{2.02 g H_{2}}{1 mol H_{2}} * \frac{1 kg}{1000 g}= 26.2 kg H_{2}$

2) Mass of sodium = $1.3 * 10^{21} atoms Na * \frac{1 mol Na}{6.022* 10^{23}atoms Na} * \frac{22.99 g Na}{1 mol Na} = 0.0496 g Na$

3) Mass of mercury = $1.2 mL * 13.6 \frac{g}{mL} = 16.32 g$

Number of atoms of mercury = $16.32 g Hg * \frac{1 mol Hg}{200.59 g Hg} * \frac{6.022* 10^{23} atoms Hg}{1 mol Hg} = 4.9 * 10^{22} atoms Hg$
