Answer:
0.13 L
Explanation:
Given data:
Initial volume of NaOH = ?
Initial molarity = 9.0 M
Final molarity = 1.0 M
Final volume = 1.2 L
Solution:
Formula:
M₁V₁ = M₂V₂
M₁ = Initial molarity
V₁ = Initial volume
M₂ = Final molarity
V₂ = Final volume
now we will put the values in formula.
9.0 M × V₁ = 1.0 M × 1.2 L
9.0 M × V₁ = 1.2 M.L
V₁ = 1.2 M.L/ 9.0 M
V₁ = 0.13 L
0.13 L of 9.0 molar solution of NaOH must be used to make 1.2 L of 1.0M solution.
