The mole ratio of the compound and its constituent elements are as follows:

  1. The mole ratio between the compound and O is 5 : 22
  2. The mole ratio between the compound and Si is 2 : 4
  3. The mole ratio between the compound and Ca is 5 : 20
  4. The mole ratio between the compound and C is  1 : 1

What is mole ratio?

Mole ratio is the ratio of the moles of one or more elements or compounds to another.

The given compound is Ca₄Si₂O₆(CO₃)(OH)₂

Moles of oxygen present in 1 mole of compound = 11 moles

Moles of Si present in 1 mole of compound = 2 moles

Moles of Ca present in 1 mole of compound = 4 moles

Moles of C present in 1 mole of compound = 1 mole

  1. Given 5 moles of the compound below, the mole ratio between the compound and O is 5 : 22
  2. Given 2 moles of the compound below, the mole ratio between the compound and Si is 2 : 4
  3. Given 5 moles of the compound below, the mole ratio between the compound and Ca is 5 : 20
  4. Given 3.5 moles of the compound below, the mole ratio between the compound and C is  1 : 1

Given the equation of the reaction below;

  • Pb(NO₃)₂ (aq) + 2 KI (aq) --> PbI₂ (s) + 2 KNO₃ (aq)

the mole ratio of the reactants and products are as follows:

  • Pb(NO₃)₂ : 2 KI (aq) = 1 : 2
  • Pb(NO₃)₂ : PbI₂ (s0 = 1 : 1
  • Pb(NO₃)₂ : 2 KNO₃ (aq) = 1 : 2

In conclusion, the mole ratio of reaction is the ratio in which moles of the substances combine.
