A gas sample is collected at 19.0?C and 1.90 atm. If the sample has a mass of 9.00 g and a

volume of 4.00 L, ?nd the volume of the gas at STP.

Answer in units of L

Solution

P = 1.9 atm

T = 19C = 292K

V = 4L

PV = nRT

R = 0.082

n = 0.3174

so at STP P = 1atm

T = 298K

so V = nRT/P

V = 7.756 L..............ANS
