Question

Quizplus · Accepted Answer

To calculate the molar mass of Ba(C₂O₄)₂, we need to add up the atomic masses of all the atoms in the compound. Ba: 137.33 g/mol C: 12.01 g/mol S: 32.06 g/mol U: 238.03 g/mol B: 10.81 g/mol O: 15.99 g/mol There are twelve Cs, fourteen Ss, and one O in the compound, but only one of each of the other elements. So, we can calculate the total molar mass as follows: (1 × 137.33) + (12 × 12.01) + (14 × 32.06) + (1 × 15.99) + (1 × 10.81) + (1 x 238.03) = 225.34 g/mol Therefore, the correct answer is D.
