A chemist must prepare 575.mL of 1.00M aqueous sodium carbonate Na2CO3 working solution. He'll do this by pouring out some 1.58M aqueous sodium carbonate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the sodium carbonate stock solution that the chemist should pour out. Round your answer to 3 significant digits.

Answer : The volume in mL of the sodium carbonate stock solution is 364 mL.

Explanation :

According to dilution law:

where,

= molarity of aqueous sodium carbonate

= molarity of aqueous sodium carbonate stock solution

= volume of aqueous sodium carbonate

= volume of aqueous sodium carbonate stock solution

Given:

= 1.00 M

= 1.58 M

= 575 mL

= ?

Now put all the given values in the above formula, we get:

Therefore, the volume in mL of the sodium carbonate stock solution is 364 mL.
