So Question 4 asks, Calculate the amount of solid sodium
hydroxide needed to make 200mL of a 0.2M solution.
My work is as follows:
.2mol/1L•.200L=0.04mol
.04mol•40g/1mol= 1.6 grams
Question 5 asks, If 10mL of the solution made in question 4 is used to make another 125mL solution of NaOH, what is the new concentration?

You work in a research lab with a chemist who asks you to make 500.0 mL of a formic acid/sodium formate buffer solution with pH = 4.10. Formic acid is HCOOH(aq); sodium formate is NaHCOO(s) and is soluble in water. The total concentration of formic acid + formate ion in the buffer is to be 0.120 M. Ka(HCOOH) = 1.77 × 10–4 (pKa = 3.75). In the storeroom, there are the following reagents: (i) solid sodium formate, (ii) a 3.00...
