Answer is: <span>molality of a nonvolatile, nonelectrolyte solute is 15,38 m.
</span>ΔT = 8°C.
Kb = 0,520°C/m.
b = ?
ΔT = Kb · b.
8°C = 0,520°C/m · b.
b = 15,38 m = 15,38 mol/kg.
Nonelectrolyte means that compound has very little dissociation in water.

The rock had a mass of 500g and a density of 10 g/cm3. What is the volume of the rock
NARA [144]

lets work back. The formula to find density is d= m/v. fill in the values you know.

10 = 500/v

well, we don't need to use a calculator. dividing by ten is going to the left once, and removing one value of ten.

this means you have a volume of 50. 

Hope this helps! :D

the energy that is present in the gasoline in your automobile's fuel tank is a. potential energy b. nuclear energy c. kinetic en
Softa [21]
A. potential energy.
It can't be any of the above questions. When the automobile burns gas it converts the potential energy into chemical energy which intern gets converted into mechanical energy and then into kinetic energy.

I would have thought it would be Chemical potential energy, which is referring to the energy between the bonds in the molecule.
