What is mole fraction of liquid?

Mole fraction describes the number of molecules (or moles) of one component divided by total the number of molecules (or moles) in the mixture.

What is the mole fraction of H2O?

Mole fraction of A in H2O is 0.2.

What is mole fraction class 12?

Class 12 Chemistry Solutions. Mole fraction. Mole fraction. Mole fraction can be defined as the ratio of number of moles of the component in the solution to the total number of moles of all components in the solution.

What is mole fraction class 11 Ncert?

Mole fraction is equivalent to the ratio of moles of a specific component to the number of moles of solution. … The mole fraction is the ratio of the number of moles of one component to the total number of moles of the solution (i.e., all the components).

What is mole fraction class 9?

What is the mole fraction of 1 Litre pure water?

Thus, the molarity of pure water is 55.56 moles per litre. So, option C is the correct one. Note: We have to change the unit of density of water from gm/ml to Kg/L to calculate the molarity of pure water.

What is the mole fraction of 1 molal aqueous solution?

Solution: 1 molal aqueous solution means 1 mole of solute in 1 kg (or 1000 g) of water. The molecular weight of water is 18 g/mol. Thus, option D is correct.

What is the mole fraction symbol?

The symbol for the mole fraction is the lower-case Greek letter chi, χ. You will often see it with a subscript: χsolute is an example.

What is the unit of mole fraction in chemistry?

D. Mole fraction is a unit of concentration, defined to be equal to the number of moles of a component divided by the total number of moles of a solution. Because it is a ratio, mole fraction is a unitless expression. The mole fraction of all components of a solution, when added together, will equal 1.
