Question

Can somebody show me how to figure out the following exampleproblems? 1)A sample of nitrogen at 20.0 °C has a volume of 1,027 mLat a pressure of 1,184 mmHg. To change the volume to 1,962 mL, whatmust be the new pressure?
2)What would be the volume of a balloon filled with 4.77 L ofH2 gas collected at 1,553 mmHg if the pressure wereincreased to 2,131 mmHg?

Explanation / Answer

Assuming that the temperature is constant, P1 = 1184 mmHg,   V1 = 1027 mL V2 = 1962 mL P1 V1 = P2 V2 New pressure, P2 = P1 V1 / V2                             = 1184 mm Hg * 1027 mL / 1962 mL                              =619.75 mm Hg Similarly, V1 = 4.77 L P1 = 1553 mmHg P2 = 2131 mmHg Volume, V2 = P1 V1 / P2 Substitute the values and simplify to get the answer.
