HELP PLZ!!!

400.0 ml of a 0.789 M H2SO4 solution is diluted to 750.0 ml. What is the concentration of the diluted solution?

Answer 1

The concentration of diluted solution is found to be 0.421 M

Step-by-step explanation:

It is given that a stock solution (400 ml) should be diluted to 750 ml, we need to find the concentration of the diluted solution using the Law of Volumetric analysis,

V1M1 = V2M2

V1 being the volume of the stock solution = 400 ml

M1 being the molarity of the stock solution = 0.789 M

V2 being the volume of the diluted solution = 750 ml

M2 being the molarity of the diluted solution = ?

Now we have the molarity of the diluted solution by rearranging the above equation as,

M2 =
`$(V1M1)/(V2)`

Now plugin the values as,

M2 =
`$(400 ml * 0.789 M)/(750 ml )`

= 0.421 M

So the molarity of diluted solution is found to be 0.421 M.
