Asked Nov 7, 2019

5.324 L of a gas is collected at 25.0°C and 846.0 mmHg. When the gas is changed to STP conditions, what is the new volume?

Step 1

As per the initial conditions given, first it is required to calculate the number of moles of gas present by using the ideal gas equation

PV nRT
P 846 mm Hg = 846/760 = 1.11 atm
V 5.324 L
T
25 °C 25 273 298 K
R
0.082 L atm K-1 mol-1

Step 2

Substituting the values,

PV nRT
x 0.082 x 298
1.11 x 5.324 n
n 0.242 moles
