Question

A sample of oxygen gas contains 1.30 moles of 02 and occupies a volume of 2.0 L. If this sample of gas is transferred to a 3.0 L container, how many more moles of zero 2 need to be added so that the same pressure and temperature is obtained?

a. 0.65 mol
b.0.86 mol
c.1.95 mol
d.4.62 mol

Answer 1

Answer:

According to ideal gas equation

PV =nRT

Given n1=1.30 moles

v1 =2lit

Explanation:

n2= x moles

V2 = 3lit

v1/v2 = n1/n2 2/3 = 1.3/x

x= 3.9÷2 x = 1.95

The correct option is c
