I suppose H2 as an ideal gas and the initial volume is 0 according to the initial conditions of this exercise. I suppose the pressure is 1.0 atm
The temperature in Kelvin degrees is 303K (40oC=303K) adding 273 to Celsius degrees temperature.
Final volume is 80.0ml.
Let`s start to use the ideal gas equation:
P=1.0atm
V=80.0ml
T=303K
The number of moles of hydrogen is calculated by this equation:
FW H2=2.0g/mol
I must replace last equation into the ideal gasses equation:

Sometimes in lab we collect the gas formed by a chemical reaction over water (see sketch at right). This makes it easy to isolate and measure the amount of gas produced water chemical action Suppose the CO gas evolved by a certain chemical reaction taking place at 50.0 °C is collected over water, using an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 107. mL. Sketch of...
