Question

A gas sample has 1.65 moles and occupies 3.50 L. What volume will it occupy with 2.60 moles?

Answer 1

answer and explanation

Given:

V1 = 3.50 liters

n1 = 1.65 mols

n2 = 2.60 mols

V2 = unknown

solution

to determine the volume that will be occupied by 2.60 mols we can use to following equation

V1/V2 = n1/n2

and we can rearrange the equation to make V2 subject of the formula like so:

V2 = V1n2/n1

= 3.50L x 2.60mols/1.65 mols

= 5.5 liters

2.60 mols will occupy a volume of 5.5 liters
