Answer is: <span>the approximate molar mass of a molecular solute is 150 g.
</span>m(molecular solute) = 300 g.
m(water) = 1000 g ÷ 1000 g/kg = 1 kg.
ΔT = 101°C - 100°C = 1°C.
M(molecular solute) = Kb · m(molecular solute) / m(water) · ΔT.
M(molecular solute) = 0,512°C/m · 300 g / (1 kg · 1°C).
M(molecular solute) = 153,6 g/mol.

Explanation:
I just did this and these were the answers :)
Answer:
70
Explanation:
20 x 5 vials = 100mg
therefore 5 vials required each day.
Two weeks = 14 days
14 days x 5 vials = 70 vials
Answer:
Explanation:
Hello, since the Gibbs' phase rule states the following equation:
Whereas C is the number of components and P the present phases, you answers are:
1. F=1-2+2=1.
2. F=2-2+2=2.
3. F=2-2+2=2.
Best regards.
