# Stoichiometry: Conversion Factors, Moles to Moles of Reactants

CHEM-1HOBYD

Below is a balanced equation for the reaction of nitrogen with hydrogen to produce ammonia.

Which conversion factor(s) would be used if the moles of hydrogen was given and the moles of nitrogen needed for a complete reaction had to be calculated?

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

Select ALL that apply.

A

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

B

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

C

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

D

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

E

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

F

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

G

$\cfrac{1\ mole\ N_{2}}{3\ mole\ H_{2}}$

H

$\cfrac{3\ mole\ H_{2}}{1\ mole\ N_{2}}$
