Explanation Mass of CuSO 4 ⋅ 5H 2 O is given as 360 g . The molar mass of CuSO 4 ⋅ 5H 2 O is calculated as shown below; Molar mass = 1 × M ( Cu ) + 1 × M ( S ) + 4 × M ( O ) + 5 × M ( H 2 O ) = 1 ( 63.55 g ⋅ mol − 1 ) + 1 ( 32.06 g ⋅ mol − 1 ) + 4 ( 16.00 g ⋅ mol − 1 ) + 5 ( 18.016 g ⋅ mol − 1 ) = 63.55 g ⋅ mol − 1 + 32.06 g ⋅ mol − 1 + 64.00 g ⋅ mol − 1 + 90.08 g ⋅ mol − 1 = 249.69 g ⋅ mol − 1 One mole of CuSO 4 ⋅ 5H 2 O contains five moles of water. This means 249.69 g ⋅ mol − 1 of CuSO 4 ⋅ 5H 2 O contains 90.08 g ⋅ mol − 1 of water. Therefore, the amount of water present in 360 g of CuSO 4 ⋅ 5H 2 O is calculated as follows; m ( H 2 O ) = 360 g CuSO 4 ⋅ 5H 2 O × 1 mol CuSO 4 ⋅ 5H 2 O 249
