Question

A balloon is filled to a volume of 1.50 L with 3.00 mol of gas at 25 C. with pressure and temperature held constant, what will be the volume of 1.40 moles of gas are added?

Answer 1

3.2L

Step-by-step explanation:

PV=nRT

since pressure and temperature are held constant we have V=nR

R is a constant also,

Thus;
`(v1)/(n1)=(v2)/(n2)`

v1=1.5L , n1=3mol, n2=1.4mol

`(1.5)/(3)=(v2)/(1.4)`

v2=
`(1.5)/(3)*1.4`

v2=3.2L
