Question

When magnesium oxide (MgO) and water (H20)react, they produce magnesium hydroxide Mg(OH)2. Magnesium hydroxide is a medicine used to treat an upset stomach. The equation for this chemical change is shown below:

MgO + H20 --> Mg(OH)2

if 40.00 grams of magnesium oxide and 18.00 grams of water are combined in this reaction, what will be the mass of the product? Explain.

Answer 1

This is a limiting reagent problem and you know that because amounts are given for BOTH reactants. I worked a problem just a few minutes ago and here is a link. Just follow the same steps.
