Answer:
How much of a 0.250 M sucrose solution must be used to prepare 400.0 mL of a 0.0310 M solution?
49.6 mL
Correct
Which statement best explains how the solution should be made?
Add 49.6 mL of 0.250 M sucrose to 400.0 mL of water to get 400.0 mL of 0.0310 M sucrose.
A. Add 49.6 mL of 0.0310 M sucrose to 350.4 mL of water to get 400.0 mL of 0.250 M sucrose.
B. Add 49.6 mL of 0.250 M sucrose to 350.4 mL of water to get 400.0 mL of 0.0310 M sucrose.
C. What is the molarity of the solution that results when 25.0 mL of 0.513 M solution is diluted to 500.0 mL?
Correct
0.0257 M
Correct
