The goal of the first part of the experiment is to determine the value of n in the formula for sodium percarbonate, Na2CO3·n H2O2. This will not be a whole number as sodium percarbonate is a non-stoichiometric compound (Links to an external site.). Titration of a 25.0 mg sample of sodium percarbonate revealed that it contains 0.229 millimoles of hydrogen peroxide. Using this amount, the molar masses of hydrogen peroxide and sodium carbonate, and the law of conservation of mass, determine the value of n implied by this data

The goal of the first part of the experiment is to determine the value of n in the formula for sodium percarbonate, Na2CO3·n H2O2. This will not be a whole number as sodium percarbonate is a non-stoichiometric compound (Links to an external site.).
Titration of a 25.0 mg sample of sodium percarbonate revealed that it contains 0.229 millimoles of hydrogen peroxide. Using this amount, the molar masses of hydrogen peroxide and sodium carbonate, and the law of conservation of mass, determine the value of n implied by this data.
