What is the molar mass of Cr2(SO4)3?
O 148.1 g
0 288.0 g
O 344.2 g
0 392.2 g
200.0 g

392g

Explanation:

The given compound is;

         Cr₂(SO₄)₃

To find the molar mass, we sum the atomic masses of the elements in the compounds together.

Atomic mass of Cr  = 52

                           S  = 32

                            O  = 16

So;

 Molar mass  = 2(52) + 3[32 + 4(16)]  = 392g/mol

c. 75.7

i think that is the right
