Question

Hydrogen and oxygen combine by the rate of 1:8 by mass to form water. What mass of oxygen would be required to form 3g of hydrogen gas?​

Answer 1

Answer:

Atoms And Molecules

It is given that the ration 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 x 3g=24g.

Hope it helps you...

Answer 2

Answer:

24 g

Explanation:

hydrogen and oxygen combine by the rate of 1:8

so,1=3,8=24

3:24

so mass of oxygen 24
