5.3 g of sodium carbonate have been dissolved in 500 mL of the solution. What is the molarity of the solution ?

Explanation

To find the molarity of the sodium carbonate solution, we can follow these steps:

### Step 1: Calculate the number of moles of sodium carbonate (Na2CO3)
To calculate the number of moles, we use the formula:

\[ \text{Number of moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \]
