Question

carbon and oxygen combine in the ratio of 3:8 by mass to form carbon dioxide. what is the mass of Oxygen will be required to combine completely with 4-5g of carbon? what would be the mass of carbon dioxide produced?​

Answer 1

Answer:

Let the weight of carbon used to react be x. Thus,

x/32 = 3/8

Therefore,

x = 3/8 × 32

x = 12g.

Therefore the weight of carbon to be used for complete combustion of 32g of oxygen is 12g
