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

Explanation:
Answer:
The answer is <em><u>A</u></em>.
Cations are formed when an atom or group of atom loses one or more electrons. The resulting species has more protons than electrons, so it has an overall positive charge.
The deeper you dig into soil, the wetter it is.
