Question

Quizplus · Accepted Answer

To calculate the molar mass of the compound, we need to add up the atomic masses of all the atoms in the formula unit. Ca(BO₂)₂·6H₂O can be simplified to CaB2O4S2·6H2O (using Hill notation). The atomic masses (in g/mol) are: Ca: 40.08 B: 10.81 O: 15.99 S: 32.06 H: 1.01 So the molar mass is: (40.08) + 2(10.81) + 4(15.99) + 2(32.06) + 12(1.01) + 6(18.02) = 233.80 g/mol. Therefore, the correct answer is B.
