Use the periodic table to answer this question. decomposing calcium carbonate yields calcium oxide and carbon dioxide. what information is needed to calculate the mass of calcium oxide that can be produced from 4.7 kg of calcium carbonate?

Answer : The mass of calcium oxide produced is, 2632 g

Solution : Given,

Mass of calcium carbonate = 4.7 Kg = 4700 g      (1 Kg = 1000 g)

Molar mass of calcium carbonate = 100 g/mole

Molar mass of calcium oxide = 56 g/mole

First we have to calculate the moles of calcium carbonate.

Now we have to calculate the moles of calcium oxide.

The balanced decomposition reaction will be,

From the balanced reaction we conclude that,

As, 1 mole of calcium carbonate decompose to give 1 mole of calcium oxide

So, 47 moles of calcium carbonate decompose to give 47 moles of calcium oxide

Now we have to calculate the mass of calcium oxide.

Therefore, the mass of calcium oxide produced is, 2632 g
