NEET Chemistry: Solutions — MCQ Test 7

Q6. What is the boiling point elevation of a solution containing 5 g of glucose (molar mass = 180 g/mol) in 250 g of water? (\( K_b = 0.52 \, \text{K kg mol}^{-1} \))

Q7. A solution is prepared by mixing 50 g of a solute with 150 g of water. If the solute’s mass percentage in a second solution (made with the same solute and water) is 40%, what mass of water is required for the second solution?

Q8. What is the molar mass of a solute if 5 g of it in 250 mL of solution produces an osmotic pressure of 0.984 atm at 27°C? (\( R = 0.0821 \, \text{L atm mol}^{-1} \text{K}^{-1} \))

Q9. The van’t Hoff factor of a 0.05 m NaCl solution is 1.9. What is the osmotic pressure at 27°C? (\( R = 0.0821 \, \text{L atm mol}^{-1} \text{K}^{-1} \), assume 1 L solution)

Q10. A solution of two volatile liquids has vapor pressures of 250 mm Hg and 350 mm Hg for pure components. If the total vapor pressure is 310 mm Hg, what is the mole fraction of the first component in the vapor phase?
