Question

How many moles of a gas sample are in a 10.0 L container at 373 K and 203 kPa? the gas constant is 8.31 L -kPa/ mol-K.

A. 0.33
B. 0.65
C. 1.11
D. 3.05

Answer 1

I believe the answer is 0.33

Answer 2

0.654 moles of gas

Step-by-step explanation:

GIVEN DATA:

Here Volume =10.0 litre=10 dm3

Pressure=203kPa

Temperature:373k

R= gas constant=8.31 L -kPa/ mol-K.

REQUIRED DATA:

n=moles of gas sample

CALCULATION:

FROM GENERAL GAS EQUATION

PV=nRT

n=PV/RT

PUTTING THE VALUE WE GET

n=(203*10)/(8.31*373)

n=0.654 moles
