What is the concentration of D_2O in heavy water (density 1.11 g/ml)?
What is the concentration ofin heavy water (density 1.11 g/ml)?
Select an option to attempt
Correct Answer: Option D
Explanation
Concentration of D2O (heavy water) given density = 1.11 g/mL:Molar mass of D2O:Density = 1.11 g/mL = 1110 g/LMolarity:Note: This is analogous to calculating the molarity of pure water (H2O):. D2O is slightly denser and slightly heavier, giving a very similar (~55.5 M) answer.Answer: 55.5 M (Option 4).
