Sample of 200mls of 0.5 sulphuric acid,was asked to produce 1.2M of the new solution.Calculate the volume of the new solution​
uysha [10]

Answer: The volume of the new solution​ is 83.33 mL.

Explanation:

Given: V_{1} = 200 mL,    M_{1} = 0.5 M

V_{2} = ?,             M_{2} = 1.2 M

Formula used to calculate the volume of new solution is as follows.

M_{1}V_{1} = M_{2}V_{2}

Substitute the values into above formula as follows.

M_{1}V_{1} = M_{2}V_{2}\\0.5 M \times 200 mL = 1.2 M \times V_{2}\\V_{2} = 83.33 mL

Thus, we can conclude that volume of the new solution​ is 83.33 mL.
