Question

Hydrogen and oxygen are added in a ratio of 1: 8 to produce water. How many grams of oxygen are needed to fully combine with 3 grams of hydrogen​

Answer 1

Answer:

here's ur answer mate

Explanation:

It is given that the ratio of hydrogen and oxygen by mass to form water is 1:8. Then, the mass of oxygen gas required to react completely with 1g of hydrogen gas is 8g. Therefore, the mass of oxygen gas required to react completely with 3g of hydrogen gas is 8 × 3g = 24 g.

hope it helps

Answer 2

Answer:

Since the ratio is 1:8, if we add 3 grams of hydrogen, we will have to add 3*8 = 24 grams of oxygen.
