Question

hydrogen and oxygen combine in the ratio of 1:8by mass to form water what mass of oxygen gas would be required to react completely with 3g of hydrogen gas

Answer 1

Let the required mass of hydrogen be x gram

Therefore, 1/8=x/3
x=3/8
=0.375

Therefore, 0.375 grams of oxygen is required to react with 3 grams of hydrogen to water.
