Stoichiometry: Conversion Factors, Mass Reactant to Moles Product

CHEM-5N1SBM

Below is a balanced equation for the reaction of nitrogen with hydrogen to produce ammonia. Which conversion factor(s) would be used if the mass (in g) of hydrogen was given to react with excess nitrogen, and moles of ammonia produced needs to be calculated?

$$N_{2}(g)\ +\ 3H_{2}(g)\rightarrow 2NH_{3}(g)$$

Check ALL that apply.

A

$\cfrac{2.0159\ g\ H_{2}}{1\ mole\ H_{2}}$

B

$\cfrac{1\ mole\ H_{2}}{2.0159\ g\ H_{2}}$

C

$\cfrac{17.0337\ g\ NH_{3}}{1\ mole\ NH_{3}}$

D

$\cfrac{1\ mole\ NH_{3}}{17.0337\ g\ NH_{3}}$

E

$\cfrac{6.022\times 10^{23}\ molecules}{1\ mole\ H_{2}}$

F

$\cfrac{1\ mole\ H_{2}}{6.022\times 10^{23}\ molecules}$

G

$\cfrac{2\ mole\ NH_{3}}{3\ mole\ H_{2}}$

H

$\cfrac{3\ mole\ H_{2}}{2\ mole\ NH_{3}}$
