Thank you for the opportunity to help you with your question!

a)  First convert the given mass of NaOH to volume (in mL) using the density of NaOH which is 2.13 g/mL. 
Volume of solute (NaOH)  = 34 g * (1 mL/2.13 g) = 15.96 mL 

Volume % = (volume of solute / volume of solution) * 100% 
Volume % = (15.96 mL/120 mL) * 100% = 13.3 %  (answer)

b. Volume % = volume of NaOH/ total volume 

volume % = 10 % = 10/100 = 0.10 
0.10 = 15.96 mL/total volume 
Solving for total volume yields: 

V_total = 15.96 /0.10 = 159.6 mL 
So, about 159.6  mL of a 10% solution can be made from the solution in part a.

Please let me know if you need any clarification. I'm always happy to answer your questions.
