Determine the final concentration when 250mL of 3M solution is dilluted to a final volume of 850mL. (Enter Number)​
LenKa [72]

Answer:

M₂ = 0.9 M

Explanation:

Given data:

Initial Volume = V₁ = 250 mL

Initial molarity = M₁= 3 M

Final volume = 850 mL

Final molarity = ?

Solution:

M₁V₁ = M₂V₂

M₂ = M₁V₁ /V₂

M₂ = 3 M × 250 mL / 850 mL

M₂ = 750 M / 850

M₂ = 0.9 M
