36 g of HCl dissolves in 100 g of solution. The density of HCl is 1.19 gcm-3. The molar mass of the HCl solution will be:
Correct answer: A. 36.5 g/mol
- A. 36.5 g/mol
- B. 38.0 g/mol
- C. 100 g/mol
- D. 11.73 g/mol
Explanation
Explanation:Ar of H is 1 and Ar of Cl is 35.5. Mr = 35.5 + 1 = 36.5 g/mol

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.
