Answer to Question #20569 in Organic Chemistry for Sadaam Ahmed

Question

What volume of 5.0% (m/v) solution of sodium chloride, NaCl aq), can be made using 40 g of NaCl(s)?

Answer 1

Volume percent = weight of solute * 100% / volume of solution
5.0 % (m/v) is 5 g of NaCl in 100 mL of solution Thus,
5.0 % = 40 g * 100% / V(solution)
V(solution) = 40 g * 100% / 5.0 % = 800 mL
Answer:
800 mL of 5.0% (m/v) solution of sodium chloride, NaCl, can be made using 40 g of NaCl(s).
