Question

What is the percent of water (by mass) in Na2SO4 * 10H2O? 5.00 grams of a sample of hydrated PtCl2 are heated and lose 1.50 grams of water: How many moles of water are combined with each mole of PtCl2? Analysis of a sample of hydrated salt e shows that it contains 4.86 g Mg; 6.20 g P, and 11.20 g O and 5.40 g H2O. What is the formula of the hydrated salt?

Step 1

Given that the molar mass of Na2SO4 is 142.04 g/mol and the molar mass of H2O is 18.02 g/mol, we can calculate the molar mass of Na2SO4 * 10H2O: Molar mass of Na2SO4 * 10H2O = 142.04 + 10(18.02) = 322.24 g/mol The mass of water in Na2SO4 * 10H2O is 10(18.02) = Show more…
