Question

4 gm of hydrogen reacts with 20gm oxygen to form water. The mass of water formed is

Answer 1

Mass of hydrogen = 4gm
Mass of oxygen = 20gm
Total mass of water=mass of hydrogen +mass of oxygen
= 4gm + 20gm =20gm

Answer 2

Answer:

We know that,  1 g of hydrogen reacts with oxygen = 8 g

Therefore,  3 g of hydrogen reacts with oxygen = 8 x 3 = 24 g

Thus, 24 g of oxygen gas would be required to react completely with 3 g of hydrogen gas.
