Question

A sample of `NO_2` occupies a volume of 2.3 L at 740 mm Hg. What volume would result if the pressure were increased to 760 mm Hg?

Answer 1

From Boyle's Law, `P_1V_1=P_2V_2`, if `"temperature"` and `"amount"` of gas are constant.

Explanation:

And given this proportionality, we don't have to pfaff about with units.

`V_2=(P_1V_1)/P_2=(740*mm*Hgxx2.3*L)/(760*mm*Hg)`

The volume thus reduces slightly.
