question

A Dumas bulb is filled with chlorine gas at the ambient pressure and is found to contain 7.1 g of chlorine when the temperature is T°K. The bulb is then placed in a second thermostat bath whose temperature is 30°C hotter than the first one. The stopcock on the bulb is opened so that the chlorine-gas pressure returns to the original value. The bulb is now found to contain 6.4 g of chlorine. Calculate the value of the original temperature. If the volume of the bulb was 2.24 liters, what was the ambient pressure? The atomic weight of chlorine is 35.5.
