Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Identify the elements in KBr
KBr is composed of two elements: - Potassium (K) - Bromine (Br)
Step 3:: Look up the atomic masses
- Atomic mass of Potassium (K): $$39.0983 \mathrm{g/mol}
- Atomic mass of Bromine (Br): 79.904 \mathrm{g/mol}
Step 4:: Calculate the molar mass by adding the atomic masses
\mathrm{Molar~Mass} = 118.9623 \mathrm{g/mol}
\mathrm{Molar~Mass} = 39.0983 \mathrm{g/mol} + 79.904 \mathrm{g/mol}
Final Answer
The molar mass of KBr is 118.9623 \mathrm{g/mol}.
