Question

1.A balloon contains 0.131mol of gas and has a volume of 2.65L .If an additional 0.113

mol of gas is added to the balloon (at the same temperature and pressure), what will its final volume be?

2.In the mid 1600s, the Irish chemist Robert Boyle carried out experiments that determined the quantitative relationship between the pressure and volume of a gas. His data showed that for gas at a constant temperature, pressure and volume areinversely proportional.A 12-liter tank contains helium gas pressurized to 160

Explanation / Answer

1) m1v1=m2v2

(.131)(2.65)=(.113)(v2)

v2= 3.07 L

2) p1v1=p2v2

(160)(12)=1(v2)

1920 L= 1.92 x 10 ^3

3)

a) B

b) A
