Energy leaves the Sun's core and goes by radiation, convection, and radiation on its way to the surface.

Energy leaves the sun's core and initially travels towards the radiation zone. In the radiation zone, the gas is tightly compressed. Here, electromagnetic waves are absorbed and reradiated to transfer energy. Energy can take more than 100,000 years to get through this area because it is so dense.

Thus, energy radiates out initially from the core before being delivered by convection to the outer layers.

Calculate the mole fraction of cai2 in an aqueous solution prepared by dissolving 0.400 moles of cai2 in 850.0 g of water.
alukav5142 [94]
1) Formulas:

a) mole fraction of component 1, X1

X1 =  number of moles of compoent 1 / total number of moles

b) Molar mass = number grams / number of moles => number of moles =  number of grams / molar mass


2) Application

Number of moles of CaI2 = 0.400

Molar mass of water = 18.0 g/mol

Number of moles of water: 850.0 g / 18.0 g/mol = 47.22 mol

Total number of moles = 0.400 + 47.22 =47.62

Molar fraction of CaI2 = 0.400 / 47.62 = 0.00840
