Question

please help with all the parts in this question, it is practice so I want to have all the parts to study

**Calculate the molarity of the two solutions.**

**The first solution contains 0.450 mol of NaOH in 1.25 L of solution.**

- Molarity: [Input Box] M

**The second solution contains 16.3 g of NaCl in 749 mL of solution.**

- Molarity: [Input Box] M

**Explanation:**

To find the molarity of a solution, use the formula:
\[ \text{Molarity (M)} = \frac{\text{moles of solute}}{\text{liters of solution}} \]

For the first solution:
- Moles of NaOH = 0.450 mol
- Volume = 1.25 L

For the second solution:
- Mass of NaCl = 16.3 g
- Volume = 749 mL = 0.749 L
- Molar mass of NaCl = approximately 58.44 g/mol

Convert the mass of NaCl to moles using its molar mass to find the molarity.
