Answer and Explanation:

The molar mass of a substance is all of the weights from the elements combined.

So, we have the elements

CU, S, and O_{4}

CU has a mass is 65

S mass is 32

O has a mass of 16, but there's 4 atoms of O, so we do 16 times 4, which is 64.

Now we add.

65 + 32 + 64 is 161.

<u>So, the answer is 160, or answer choice A.</u>

Zinc-bromide is its name. Since you have a metal and a non metal you don’t need to use the prefix “di” for the Br.
