To what volume in .... must 50.0ml of 3.50M H2SO4 be diluted in order to make 2 M H2SO4?
Correct answer: C. 87.5
- A. 25
- B. 60.1
- C. 87.5
- D. 93.2
Explanation
The correct option is c 87.5 mL M1V1=M2V2 Where, M1⇒ Molarity of the initial solution = 3.5 M V1⇒ Volume of the initial solution = 50 mL M2⇒ Molarity of the resultant solution i.e. after dilution = 2 M V2⇒ Volume of the resultant solution 3.5×50=2×V2 V2=3.5×502=87.5 mL Therefore, the initial solution must be diluted to 87.5 mL

About Concentration Units
Concentration units express the amount of solute in a given amount of solution or solvent. Calculations cover molarity, molality, normality, mole fraction, mass percentage, volume percentage, parts per million and dilution, including the effect of temperature on volume-based units and the distinction between molarity and molality.
