Moles= molarity x liter
=0.2500 M x 0.500 L
= 0.1250 mol
mass C2H2O4 . 2H2O = 0.1250 mol x (126.068 g / 1 mol)
=15.76 g
Answer:
Explanation:
By reading the statement, it is inferred that molarity must be computed. The amount of moles of hydrocloric acid is:
Finally, the molarity of the solution is:
