Answer:
20moles
Explanation:
Molarity of a solution = moles of solute / volume of solution
Therefore
Molarity of NaCl solution = moles of NaCl ÷ volume of NaCl solution
Given,
Molarity of solution = 4M
Moles of NaCl = ?
Volume of solution = 5L
4M = moles of NaCl ÷ 5L
Multiply both sides by 5
Moles of NaCl = 4×5 moles
= 20moles
