Q. If 1 mole of NaCl is dissolved in water, how many particles are present in solution?
A.
1
B.
2
C.
3
D.
4
Solution
1 mole of NaCl dissociates into 2 particles (1 Na⁺ and 1 Cl⁻), so there are 2 particles in solution.
Q. What is the formula for calculating the boiling point elevation?
A.
ΔT_b = i * K_b * m
B.
ΔT_b = K_b / m
C.
ΔT_b = i * K_f * m
D.
ΔT_b = K_f * m
Solution
The boiling point elevation is calculated using the formula ΔT_b = i * K_b * m, where i is the van 't Hoff factor, K_b is the ebullioscopic constant, and m is the molality.
