Question

Do you know how much water could you get if you started with 250.0 grams of hydrogen?

Answer 1

The amount of water that could we get if you started with 250.0 grams of hydrogen is 2,250 grams.

What is moles - mass realation?

Moles (n) and mass of any substance are related to each other according to the given equation as:

n = W/M, where

W = given mass

M = molar mass

Given balanced chemical reaction is:

2H₂ + O₂ → 2H₂O

Moles of 250g of H₂ = 250g / 2g/mol = 125mol

From the stoichiometry of the reaction it is clear that,

2 moles of H₂ = produces 2 moles of H₂O

125 moles of H₂ = produces 125 moles of H₂O

Now mass of water will be calculated as:

Mass = (125mol)(18g/mol) = 2,250g

Hence required mass of water is 2,250 grams.
