Question

if we began with 32.0 grams of oxygen and all of the hydrogen that you need, how many grams of water can be made?

Answer 1

36 gram of water can be made.

 The molar mass of O is 16g and Hydrogen is 1g in H2O there is one oxygen only but in question is given 32g of oxygen so, 2 moles of oxygen should be there so it will become 32g that means 2H2O so overall 2[2*1+16] = 36g.

What is Balanced equation?

When number of moles of both the reactants and products are equal then it is known as balanced chemical equation.
