(b) What amount (mol) of CaO can be produced from the given mass of O₂?
1 answer:
The amount of Ca is not limiting, we have : 2.87g of O will produce : 2.87 / 56.1 = 0,051158645 mol of CaO
What is Mass?
Mass is a property that represents the amount of matter in a sample. Mass is often expressed in grams (g) and kilograms (kg) (kg). Mass can alternatively be defined as the property of matter that provides it the ability to resist acceleration. The more mass an object has, the more difficult it is to accelerate.

Answer:
25 grams of Mg(OH)2 will be produced by 14.424 gram of Mg3N2
Explanation:
The balanced equation is
Mg3N2 + 6H2O -> 3Mg(OH)2 + 2NH3
Molecular weight of magnesium nitride = 100.9494 g/mol
Molecular weight of magnesium hydroxide = 58.3197 g/mol
one mole of Mg3N2 produces three moles of 3Mg(OH)2
100.9494 g/mol of Mg3N2 produces 3* 58.3197 g/mol of Mg(OH)2
1 gram of Mg3N2 produces
grams of Mg(OH)2
Or 1.733 grams of Mg(OH)2 will be produced by 1 gram of Mg3N2
25 grams of Mg(OH)2 will be produced by 14.424 gram of Mg3N2
