How many moles and how many grams of sodium chloride are present in 250 mL of a 0.50 M NaCl solution ?

Explanation

To solve the problem of how many moles and how many grams of sodium chloride (NaCl) are present in 250 mL of a 0.50 M NaCl solution, we can follow these steps:

### Step 1: Understand the formula for molarity
Molarity (M) is defined as the number of moles of solute divided by the volume of solution in liters. The formula is:
\[ \text{Molarity (M)} = \frac{\text{moles of solute}}{\text{volume of solution in liters}} \]
