frac{M_{B} R T}{V}=frac{M_{A} R T}{V}
(0.3 S+x) 300=(0.35-x) 400

[
begin{array}{r}
P_{2}=m_{2} R T
frac{P_{1}}{P_{2}}=frac{m_{+}}{n_{2}}
frac{0 cdot 05}{P_{2}}=frac{0 cdot 35}{0-4}
P_{2}=frac{4}{7} a sqrt{m}

# Two flask of equal volume connected by narrow tube (of negligible volume) are at 27°C and contains 0.7 moles of H2 at 0.5 atm. One of the flask is then immersed in a bath kept at 127°C, while the other remains at 27°C. Calculate the final pressure and the number of moles of H2 in each flask.
