Answer:
Molecular weight of the compound = 372.13 g/mol
Explanation:
Depression in freezing point is related with molality of the solution as:

Where,
= Depression in freezing point
= Molal depression constant
m = Molality


m = 0.26
Molality = 
Mass of solvent (toluene) = 15.0 g = 0.015 kg

Moles of compound = 0.015 × 0.26 = 0.00389 mol

Mass of the compound = 1.450 g

Molecular weight =

Answer:
Breathe. Breathing is the number one thing every human does, and their bodies need it. Think about going in a pool in 6 feet. You realize that its kinda hard to breathe and it feels like something is holding your chest down really hard. Water pressure and air pressure can affect the breathing habits of a human and can also cause suffocation to the lungs.

Considering ideal gas behavior, the volume of 1 mol of gas at STP is 22.4 L; then the volume occupied by 1.9 moles is 1.9mol*22.4L/mol
The answer is 43 L if I am correct.
