Chemical calculation problem
« on: May 25, 2020, 02:47:28 PM »
Hello guys, I am struggling with one calculation and it goes like this: Calculate, how much of CO2 is made during the reaction: 2CO+O2, if we use 33,6 dm3 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 :)

Check the chemical equation how much CO2 correpond to O2
Use the molar Volume.

Do you know Avogadro's law?
