Answer to Question #172526 in General Chemistry for Blank 0822

Question

Calculate the mole fraction of 5.65g Calcium Chloride with molar mass of 111g/mole placed in 15.5g of H2O with molar mass of 18.0g/mole.

Answer 1

The mole fraction can be calculated by dividing the number of moles of one component of a solution by the total number of moles of all the components of a solution. It is noted that the sum of the mole fraction of all the components in the solution should be equal to 1.
