Question

A sample of gas occupies 30.8 L at 325 K and 1.47 atm. How many moles of gas are present? (answer in decimal form)

Answer 1

Answer:

1.7mol or 1.69 mol

Explanation:

IDEAL GAS EQUATION;

PV=nRT

R=GAS CONSTANT

=0.0821 L atm / K mol

P=1.47 atm

V=30.8L

n=

T=325K

30.8×1.47=n×0.0821×325

n=1.69mol which is approximately=1.7 mol
