What is the volume (in liters) of 1.00 mole of krypton gas that has a pressure of 1140 mm hg and a temperature of 25.0°c? (r = 0.0821 l atm / mol k) ?

The volume (in liters) of 1.00 moles of krypton gas is 16.31 L

Calculation

The volume of krypton is calculated using ideal gas equation

that is PV=nRT where

P (pressure) = 1140 mm hg

convert 1140 mmhg into atm

= 1 atm = 760 mmhg

? atm = 1140 mm hg

by cross multiplication

= (1 atm x1140 mmhg) / 760 mmhg = 1.5 atm

V (volume) = ? L

n (number of moles) = 1.00 mole

R (gas constant) = 0.0821 L atm / mol. K

T (temperature) = 25 c into kelvin = 25+273 = 298 K

make v the subject of the formula by dividing both side by P

V = nRT/P

V = [ (1.00 mole x 0.0821 L. atm/mol. k x 298 K) / 1.5 atm ] = 16.31 L
