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