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
