what is the mole ratio of salt and water of hydrate Na2SO4• 10H2O
The mole ratio of salt (Na2SO4) to water in Na2SO4 • 10H2O can be calculated by dividing the subscripts of the salt and water molecules by their greatest common factor.
The formula shows that there are 10 molecules of water for every molecule of Na2SO4. Therefore, the mole ratio of salt to water in Na2SO4 • 10H2O is 1:10.
