Calculate the mass of oxalic acid dihydrate needed to prepare 500.0 ml

This question is incomplete.

The complete question is: Calculate the mass of oxalic acid dihydrate needed to prepare 500.0 mL of 0.2500 M oxalic acid solution.

15.75 grams

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

where,

Molarity = 0.2500 M

n= moles of solute  = ?

= volume of solution in ml = 500.0 ml

Mass of oxalic acid dihydrate =

Therefore, the mass of oxalic acid dihydrate needed to prepare 500.0 ml is 15.75 grams
