Using

#### Explanation:

You would use the equation

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

In your case:

P = 735 mmHg

V = 660 mL = .660 L

n = ?

R = 62.4

T = 27 Celsius = 27 + 273 = 300 degrees kelvin

solve for n and the answer is .0259 moles.
