7.) You need to make an aqueous solution of 0.140 M nickel(II) sulfate for an experiment in lab, using a 250 mL volumetric flask. How much solid nickel(II) sulfate should you add?

How many milliliters of an aqueous solution of 0.175 M sodium hydroxide is needed to obtain 5.85 grams of the salt?

8.)

In the laboratory you dissolve 14.0 g of nickel(II) sulfate in a volumetric flask and add water to a total volume of 250 mL.

What is the molarity of the solution?
What is the concentration of the nickel cation?

What is the concentration of the sulfate anion?

b.) In the laboratory you dissolve 17.5 g of sodium hydroxide in a volumetric flask and add water to a total volume of 125 mL.

What is the molarity of the solution?

What is the concentration of the sodium cation?

What is the concentration of the hydroxide anion?
