Question

A balloon containing 0.10 moles of gas has a volume of 2.0 liters. If temperature and pressure remain constant, what will be the new volume when 0.40 moles of gas are added to the balloon?

0.50 L
1.0 L
6.0 L
8.0 L

Answer 1

use n1/V1 = n2/V2

.1/2 = .4/V2
.1V2 = .8
V2 = 8 L or D

Answer 2

Answer:The new volume when 0.40 moles of gas are added to the balloon is 8 L.

Step-by-step explanation:

Initial moles of gas
`n_1` = 0.10 moles

initial volume of the balloon,
`V_1` = 2.0 L

Final moles of gas
`n_2` = 0.40 moles

Final volume of the balloon,
`V_2` = 2.0 L

Avogadro Law:
`(n_1)/(V_1)=(n_2)/(V_2)`

`V_2=(n_2* V_1)/(n_1)=(0.40 mol* 2.0L)/(0.10 mol)=8.0 L`

The new volume when 0.40 moles of gas are added to the balloon is 8 L.
