Answer:
250 g of sodium chloride have 4.3 moles
Explanation:
Given data:
Mass of NaCl = 250 g
Number of moles = ?
Solution:
Number of moles = mass/ molar mass
Number of moles = 250 g/ 58.5 g/mol
Number of moles = 4.3 moles
Thus 250 g of sodium chloride have 4.3 moles.

Explanation:
Let's consider the neutralization reaction between KHP and NaOH.
KHC₈H₄O₄ + NaOH → H₂O + NaKC₈H₄O₄
12.39 mL of 0.04150 M NaOH were required for the neutralization. The moles that reacted are:
12.39 × 10⁻³ L × 0.04150 mol/L = 5.142 × 10⁻⁴ mol
The molar ratio of KHP to NaOH is 1:1. The moles of KHP that reacted are 5.142 × 10⁻⁴ mol.
5.142 × 10⁻⁴ moles of KHP were in 10 mL of solution. The concentration of the KHP solution is:
5.142 × 10⁻⁴ mol / 10 × 10⁻³ L = 0.05142 M
