Question #2de95

Answer 1

For this problem we actually would use Boyle's Law comparing Pressure and Volume because the temperature is held constant.

Boyle's Law is based upon the inverse relation of the values of pressure and volume at a constant temperature. If volume increases the gas has more room and therefore less collisions take place between the molecules reducing the pressure. When the volume is reduced the gas has less room and therefore more collisions take place and pressure increases.

The basic equation is `P_1V_1 = P_2 V_2`

For the example problem given the variables are

`P_1` = 905 torr
`V_1` = 631 mL
`P_2` = 606 torr
`V_2` = ???

(905 trr) (631 mL) = (606 trr)(`V_2`)

`(905 trr) (631 mL) / (606 trr)` = (`V_2`)

942 torr = (`V_2`)
