How many grams of are needed to react with 120 g of NO, in order to obtain ?
The chemical equation is:
The molecular mass of NO is equal to (14 + 16) = 30 g/mol. Oxygen has a molecular mass of (16·2) = 32 g/mol. As you can see in the previous equation: 2·30 = 60 g of NO will need to 32 g of in order to complete the reaction. Let's go to do a mathematical proportion:
