Question

The ideal gas law describes the relationship among the pressure P, volume V, number of moles n, and absolute temperature T of an ideal gas. Here is the relationship expressed mathematically: PV = n RT where R is a proportionality constant. The units of R are determined by the units of pressure and volume used in the equation. When atm is used for pressure and i. for volume, the appropriate R value is 0.0821 L-atm/mol-K: How many air molecules are in a 11.0 times 12.0 times 10.0 ft room? Assume atmospheric pressure of 1.00 aim. a room temperature of 20.0 degree c, and ideal behavior. Volume conversion: There are 28.2 liters in one cubic foot.

Explanation / Answer

PV = NRT N = 0.821*293/1.00*1320 = 18.22
