To determine the number of moles of HCl in a solution, you will need to use the formula:
\(\[ \text{moles} = \text{molarity} \times \text{volume} \]\)
Here's a step-by-step breakdown:
1. Identify the given values:
- Volume of the HCl solution: \(\( 0.70 \)\) liters (L)
- Molarity of the HCl solution: \(\( 0.33 \)\) moles per liter (M)
2. Apply the formula for moles:
\(\[ \text{moles of HCl} = \text{molarity} \times \text{volume} \]\)
\(\[ \text{moles of HCl} = 0.33 \, \text{M} \times 0.70 \, \text{L} \]\)
3. Perform the multiplication to find the number of moles:
\(\[ \text{moles of HCl} = 0.33 \times 0.70 \]\)
4. Calculate the result:
\(\[ \text{moles of HCl} = 0.231 \]\)
Therefore, there are approximately \(\(0.231\)\) moles of HCl present in 0.70 liters of a 0.33 M HCl solution.
