(b) Two containers A and B are joined by a tube of negligible volume, as illustrated in
Fig. 2.1.
container A
3.1 × 103 cm3
17 °C
container B
4.6 × 103 cm3
30 °C
Fig. 2.1
The containers are filled with an ideal gas at a pressure of 2.3 × 105 Pa.
The gas in container A has volume 3.1 × 103 cm3 and is at a temperature of 17 °C.
The gas in container B has volume 4.6 × 103 cm3 and is at a temperature of 30 °C.
Calculate the total amount of gas, in mol, in the containers.
