Question

use the mole quick check
the atomic mass of copper (cu) is 63.546 amu, the atomic mass of sulfur (s) is 32.065, and the atomic mass of oxygen (o) is 15.999 amu. which molar mass is correct for copper sulfate (cuso₄)?
111.610 g/mol
446.440 g/mol
159.607 g/mol
225.802 g/mol

Explanation:

Step1: Analyze the formula of copper sulfate

Copper sulfate is \(CuSO_4\). It contains 1 copper atom (\(Cu\)), 1 sulfur atom (\(S\)), and 4 oxygen atoms (\(O\)).

Step2: Calculate the molar mass

The molar mass \(M\) of \(CuSO_4\) is calculated as follows:
