Question
**Problem Statement:** What volume (mL) of a concentrated solution of sodium hydroxide (6.00 M) must be diluted to 241 mL to make a 1.45 M solution of sodium hydroxide? **Options:** - ○ 2100 - ○ 0.0172 - ○ 58.2 - ○ 831 - ○ 0.036 **Action Buttons:** - Submit - Request Answer **Explanation:** This question involves the dilution of a solution. To solve it, you can use the dilution formula: \[ C1 \times V1 = C2 \times V2 \] where: - \( C1 \) is the concentration of the initial solution (6.00 M), - \( V1 \) is the volume of the initial solution you need to find, - \( C2 \) is the concentration of the final diluted solution (1.45 M), - \( V2 \) is the volume of the final solution (241 mL). By substituting the values and solving for \( V1 \), you can find the required volume of the concentrated sodium hydroxide solution.

**Question:** What volume (mL) of 0.191 M NaOH is required to neutralize 30 mL of 0.214 M HCl? **Options:** - 734 - 0.001230 - 1.230 - 33.6 - 0.0298 This question involves a titration problem where you need to find the volume of sodium hydroxide (NaOH) solution required to neutralize a given volume and concentration of hydrochloric acid (HCl). Use the formula for titration: \( M_1V_1 = M_2V_2 \), where \( M \) is the molarity and \( V \) is the volume. Calculate the appropriate volume of NaOH needed for complete neutralization.
