b. A sample of hydrogen gas occupying a volume of 2.76 L exerts a pressure of 627 torr at 27 °C. i. If the quantity of hydrogen gas in the container is tripled, calculate the new volume if the pressure and temperature remain unchanged. ii. If the quantity of hydrogen gas is reduced by one-half in the same 2.76 L container, determine the pressure exerted by the remaining gas at 27 °C. ​
