We are given with 500 mg of sucrose dissoved in a 200 ml of water. The concentration of the solid is amount of solute per volume of the solvent. The concnetration can be expressed as 2.5 grams sugar per liter water or 250 mg per 100 ml water.
Answer:
.14L or 140mL
Explanation:
This is a classic plug-n-chug problem. Your textbook probably goes over this formula as
. M stands for molarity of the given substance, and V stands for the volume that the substance occupies.
Simply plug in the values that you're given, like so:


After completing the algebra portion and solving for the unknown, you will be left with x = .14L, which is the volume required to neutralize 30mL of 7M NaOH.
