What is the concentration of your solution?

(your unknown sample is known to be about 1 m, but you need to determine the concentration to 3 significant figures using titration. you should plan ahead so that you know approximately what volume of your sample you will need in order to use approximately 25 ml of 0.100 m sulfuric acid for the titration).

The volume of unknown sample would be 2.5 mL.

Explanation:

Given data:

Molarity of unknown sample=M₁= 1 M

Molarity of sulfuric acid = M₂= 0.100 M

Volume of sulfuric acid = V₂= 25 mL

Volume of unknown sample=V₁  = ?

Solution:

Formula:

M₁V₁   =  M₂V₂

Now we will put the values in formula:

1M × V₁   =  0.100 M × 25 mL

V₁   =  0.100 M × 25 mL / 1 M

V₁   = 2.5 mL

The volume of unknown sample would be 2.5 mL.
