An important reaction which occurs in the catalytic converter of a car is
2CO(g) + 2NO(g) o 2CO2(g) + N2(g)
In this reaction, when 500 cm3 of CO reacts with 500 cm3 of NO at 650 °C (the operating temperature of the catalyst) and at 1 atm, the total volume of gases produced at the same temperature and pressure is

A 500 cm3
B 750 cm3
C 1000 cm3
D impossible to calculate without knowing the molar volume of gases under these conditions.

i don't know how to solve this. can someone explain?

You have equal number of moles of gas on each side of the reaction - which is directly proportional to volume.
