Calculate The Concentration Of Ethyl Alcohol Mixed With Water
Q44: A solution contains 40 mL of ethyl alcohol mixed with 100mL of water. What is the concentration of the solution in terms of volume by volume percentage?
Volume of solute (ethyl alcohol) = 40mL Volume of solvent (water) = 100 mL
Total volume of the solution
= 40 + 100 = 140 mL
Volume by Vol. Percentage
= Volume of solute × 100 / volume of solution
⇒ v/v % = 40 × 100 /140
