PROBLEM 47P

A balloon contains 0.128 mol of gas and has a volume of 2.76 L. If an additional 0.073 mol of gas is added to the balloon, what is its final volume?

Solution 47P

Here, we need to calculate the final volume of a gas under same condition.

We know,

Avogadro’s law states that the volume of a gas is directly proportional to the amount (in moles).

V

Thus, =

Given that,

V1 = 2.76 L

V2 = ?

n1 = 0.128 mol

n2 =0.073 mol

Therefore,

=

= 1.574 L

Therefore, the final volume of 0.073 mol of a gas under the same conditions is 1.574 L.
