1. A gas occupies a volume of 134ml at a temperature of 138degC and pressure of 542.6mmHg. What is the new volume if the temperature increases to 294degC and the pressure increases to 845mmHg?
2. What is the pressure (in atm) of a oxygen gas (O2) inside a balloon that has a volume of 3.75L and a temperature of 125degC. The mass of the gas is 14.2grams. (Hint: can you change mass to another unit you need?)
