Hello guys, I am struggling with one calculation and it goes like this: Calculate, how much of CO

_{2} is made during the reaction: 2CO+O

_{2}, if we use 33,6 dm

^{3} of O2, also calculate the amount of CO used. The only other thing given is M values(M(CO)=28, M(CO2)=44 ). The answer is 132 g of CO2 and 67,2 l. I especially don't know how I am supposed to get to the litres. Any help is appreciated
