28 grams /mol
44 grams/ mol

Answer 1

Mr(CO2) = 12+2(16)= 44g/mol

Step-by-step explanation:

In CO2 there are "2" oxygen and 1 carbon. Given the data, we add the molar masses to find the molar mass of the compound but since there are two oxygen, we multiply the molar mass of oxygen by 2 before multiplying.
