Mole fraction of solute = 156.56=0.0176.
What is mole fraction of 1 molal aqueous solution of urea?
The mole fraction of the solute in a 1 molal aqueous solution is: 1. 1.8.
What is the mole fraction of solvent in 1 molal aqueous?
1 molal aqueous solution means that 1 mol/kg that is 1 mol of solute is present in the 1000 g of the water(here the aqueous means that solvent is water). The mole fraction of solvent in 0.1 molal aqueous solution is 0.9982.
What is the meaning of molal aqueous 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.
What is the mole fraction of solute in 0.5 molal aqueous solution?
0.5 molal solution means 0.5 moles of solute in 1 kg of water. The molar mass of H2O = 18.015 g/mol.
What is the mole fraction of a solute in 2.0 molal aqueous solution?
Mole fraction of solute =(2 mol)(2 mol)+(55.55 mol)=0.347.
What is the mole fraction of h2o2?
Thus the mole fraction of hydrogen peroxide in a 30% aqueous solution of hydrogen peroxide is 0.184.
What is the mole fraction of methyl alcohol?
Therefore, the mole fraction of methyl alcohol in the solution is 0.086.
What is the molarity of 4 Naoh solution?
What is the mole percentage o2 in the mixture?
Mole percent of oxygen = x1/(x1+x2) *100 = 1/(1+0.5) *100 = 66.66 %……..
What is the unit of mole fraction?
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.
What is the molarity of pure water?
Thus, the molarity of pure water is 55.56 moles per litre.
What is molarity of 0.2 N H2So4 solution?
The molarity is half the normality. So, the molarity of 0.2 N H2So4will be 0.1 M H2So4.
What is the mole fraction of the solution in 2.5 molal aqueous solution?
Mole fraction of the solute = 2.52.5+55.56=0.043.
What is a .5 Molal solution?
5 molal solution means 5 moles of solute are dissolved in 1 kg (or 1000 g) of solvent.
What is the mole fraction of water in 2.5 M aqueous solution of a compound?
2.5 m aqueous solution means that 2.5 moles of the solute are dissolved in 1000 g of water. (2.5mol)(2.5mol+55.5mol)=(2.5mol)(58mol)=0.043.
