Calculate the molar mass of CuSO₄•5H₂O.

Question

Quizplus · Accepted Answer

CuSO₄•5H₂O consists of several different elements and subscripts. To calculate molar mass, we need to add up the atomic masses of each element present in the compound, multiplied by the number of atoms of that element in the compound. Cu: 1 x 63.55 g/mol = 63.55 g/mol S: 15 x 32.06 g/mol = 480.90 g/mol O: 14 x 15.99 g/mol = 223.86 g/mol H: 5 x 1.01 g/mol = 5.05 g/mol Total: 773.36 g/mol Rounded to two decimal places, the molar mass of CuSO₄•5H₂O is 249.69 g/mol, which corresponds to choice (B).
