Answer:
Mass = 58.5 g
Explanation:
Given data:
Volume of solution = 4 L
Molarity of solution = 0.25 M
Grams of NaCl required = ?
Solution:
Formula:
Molarity = number of moles / volume in L
By putting values,
0.25 M = number of moles / 4 L
Number of moles = 0.25 mol/L × 4 L
Number of moles = 1 mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 1 mol × 58.5 g/mol
Mass = 58.5 g
