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=nRTwhere 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 L for volume the appropriate R value is 0.0821 L·atm/mol·K.How many air molecules are in a 14.0×12.0×10.0 ft room? Assume atmospheric pressure of 1.00 atm a room temperature of 20.0 °C and ideal behavior.Volume conversion:There are 28.2 liters in one cubic foot.
