Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Identify the Chemical Formula
The chemical formula for magnesium bromide is $$MgBr_{2}$$.
This means we need to find the molar mass by adding the atomic masses of magnesium and bromine.
Step 3:: Look Up Atomic Masses
- Magnesium (Mg): $$24.305 \frac{g}{mol}
- Bromine (Br): 79.904 \frac{g}{mol}
Step 4:: Calculate the Molar Mass
- Magnesium: $$1 \times 24.305 \frac{g}{mol}
- Bromine: 2 \times 79.904 \frac{g}{mol}
Step 5:: Sum the Atomic Masses
24.305 + (2 \times 79.904) = 24.305 + 159.808 = 184.113 \frac{g}{mol}
Final Answer
The molar mass of magnesium bromide (MgBr_{2}) is 184.113 \frac{g}{mol}.
