Question

2 moles of h2 required to produce 2mole of h2o then 54 g of of h2o will produce from ?

Answer 1

Answer:

It is very hard question sorry I can't do it For you

Answer 2

Using stoichiometry, we can say that:-

Firstly write the equation

2H2 + O2 ---> 2H20

Two moles of H2 reacts with 1 mole of oxygen to get 2 moles of water.

1 mole of water = 18g

54 g = 3 moles.

2 g of H2 provides 36 g of water

----- g of H2 provides 54 g of water

cross multiply, 54 x 2/36 = 3 g of H2 is the answer.
