question 1
1. what is the molar mass of potassium carbonate (k₂co₃)?
106 g
138 g
67 g
99 g

Question

Accepted Answer

# Explanation:
## Step1: Find molar mass of each element
- Molar mass of $K$ ($M_{K}$): $39\ g/mol$
- Molar mass of $C$ ($M_{C}$): $12\ g/mol$
- Molar mass of $O$ ($M_{O}$): $16\ g/mol$
## Step2: Calculate molar mass of $K_{2}CO_{3}$
$$
\begin{align*}
M_{K_{2}CO_{3}}&=2\times M_{K}+M_{C}+3\times M_{O}\
&=2\times39 + 12+3\times16\
&=78 + 12+48\
&=138\ g/mol
\end{align*}
$$

# Answer:
138 g
