M(CO2)=12+16*2=44g/mol
Vm=22.4L/mol
n=m/M
n=8.8g/44g/mol=0.2mol
V=n*Vm
V=0.2mol*22.4L/mol=4.48L

There is the Assembly Hall on the first floor of our school. We usually gather there to mark holidays.

The dining-room and the canteen are on the ground floor. On the ground floor there is a workshop too. There we are taught to use some tools and machines.
