Question

1. What mass of water is contained in a 3.872 g sample of NaCl$\cdot$10 H$_2$O? 2. When a 3.466 g sample of a nickel(II) chloride hydrate (NiCl$_2$$\cdot n$ H$_2$O) is heated, the sample loses 1.575 g of water. Determine the empirical formula of the hydrate. 3. What is the percent (by mass) water in CaCl$_2$$\cdot$6 H$_2$O?

Step 1

44 g/mol + 10(18.02 g/mol) = 362.44 g/mol Molar mass of 10 H$_2$O = 10(18.02 g/mol) = 180.2 g/mol Mass of water = (180.2 g/mol / 362.44 g/mol) $\times$ 3.872 g = 1.93 g Show more…
