Step 1:
I'll solve this problem step by step, following the precise LaTeX formatting guidelines:

Step 2:
: Identify the elements in the compound CaSO^4

- Calcium (Ca) - Sulfur (S) - Oxygen (O)

Step 3:
: Look up the atomic masses from the periodic table

- Oxygen (O): $$m_{O} = 16.00 \mathrm{~g/mol}
- Sulfur (S): m_{S} = 32.07 \mathrm{~g/mol}

Step 4:
: Calculate the number of atoms of each element

- Ca: 1 atom - S: 1 atom - O: 4 atoms

Step 5:
: Calculate the molar mass by summing the masses of all atoms

\begin{align}
m_{CaSO_{4}} &= m_{Ca} + m_{S} + (4 \times m_{O}) \ &= 40.08 + 32.07 + (4 \times 16.00) \ &= 40.08 + 32.07 + 64.00 \ &= 136.15 \mathrm{~g/mol} \end{align}

Final Answer

The molar mass of CaSO^4 is 136.15 \mathrm{~g/mol}.
