A sample of gas occupies a volume of 50.0 milliliters in a cylinder with a movable piston. The pressure of the sample is 0.90 at

solong [7]

Answer:

The volume of sample at STP is = 41.22 ml

Explanation:

Given data

$P_{1}$ = 0.9 atm

$V_{1}$ = 50 ml

$T_{1}$ = 298 K

At STP

$P_{2}$ = 1 atm

$T_{2}$ = 273 K

From ideal gas equation

$\frac{P_1(V_1)}{T_1} = \frac{P_2(V_2)}{T_2}$

$\frac{(0.9)(50)}{298} = \frac{(1) V_2}{273}$

$V_2$ = 41.22 ml

Therefore the volume of sample at STP is = 41.22 ml
