1. When H2 gas was released by the reaction of HCl with Zn, the volume of H2 collected was 66.0 mL at 26 °C and 750 mmHg .

A. What is the volume of the H2 at 0 °C and 1.00 atm pressure (STP)?

2. Express the temperature numerically in degrees Celsius.

A. A sample of gas in a balloon has an initial temperature of 41 °C and a volume of 1800 L . If the temperature changes to 81 °C , and there is no change of pressure or amount of gas, what is the new volume, V2, of the gas?

B. What Celsius temperature, T2, is required to change the volume of the gas sample in Part A (T1 = 41 °C , V1= 1800 L ) to a volume of 3600 L? Assume no change in pressure or the amount of gas in the balloon.
