solution?

20.40g Iron(III) oxalate is dissolved in enough water to give 250.0
ml of solution. 25.00 ml of this solution is pipetted into a
100.0ml volumetric flask and diluted to the mark.
A. Calculate the molarity of Iron(III) oxalate in the original
solution.
B. Calculate the molarity of the oxalate ion in the diluted
solution.

A solution is prepared by placing 29.0 g of KCl in a 0.700 L
volumetric flask and adding water to dissolve the solid, then
filling the flask to the mark. What is the molarity of an
AgNO3 solution if 39.4 mL of the KCl solution react
exactly with 48.0 mL of the AgNO3 solution?

Felicia dissolved 4.00 g of Co(NO3)2 in enough water to make 100
mL of stock solution. She took 4.00 mL of the stock solution and
then diluted it with water to give 275 mL of a final solution. How
many grams of NO3- ion are there in the final solution?

A solution was prepared by
dissolving 26.0 g of KCl in 225 g of water.
The composition of a solution can be expressed in several
different ways. Four of the most common concentration units are
defined as follows:. mass %=mass of
componenttotal mass of solution×100%; mole fraction (X)=moles of
componenttotal moles of solution; molarity (M)=moles of
soluteliters of solution; molality (m)=moles of
solutemass of solvent (kg)
Part A
