0.5 moles of gas A and x moles of gas B exert a pressure of 200Pa in a container of volume 10 m3 at 1000 K.
Given R is the gas constant in JK−1 mol−1, x is:
4.0 g of a gas occupies 22.4L at NTP. The specific heat capacity of the gas at constant volume is 5.0 JK-1mol-1. If the speed of sound in the gas at NTP is 952 ms-1, then the heat capacity at constant pressure is.
(Take gas constant R=8.3 JK-1mol-1)
