Using $P V = n R T$, the answer is .0259 moles.

#### Explanation:

You would use the equation $P V = n R T$ (affectionately referred to as "piv-nert" by chemistry lovers)

where:
P is pressure
V is volume in liters
n is moles
R is the gas constant (its values vary depending on what unit of pressure you're using)
T is temperature in kelvin

R = 62.4 $\frac{L \cdot m m H g}{K \cdot m o l}$
$\left(735\right) \left(.660\right) = \left(n\right) \left(62.4\right) \left(300\right)$
