Answer:Sodium chloride has higher boiling point than Potassium chloride.
Explanation:This is due because potassium is larger than sodium,which means that sodium chloride has higher lattice energy in comparison to potassium chloride.
The answer i believe you are looking for is true
Answer:
Explanation:
Let’s call water Component 1 and lactose Component 2.
According to Raoult’s Law,
where
p₁ and p₂ are the vapour pressures of the components above the solution
χ₁ and χ₂ are the mole fractions of the components
p₁° and p₂° are the vapour pressures of the pure components.
Data:
m₁ = 110.0 g; p₁° = 118.0 torr
m₂ = 50.00 g; p₂° = 0 torr
1. Calculate the moles of each component
2. Calculate the mole fraction of each component
3. Calculate the vapour pressure of the mixture
