## What is the mole fraction of C12H22O11?

The required mole fraction of C12H22O11 C 12 H 22 O 11 is 1.58×10−3 1.58 × 10 − 3 .

## How do you calculate mole fraction?

The mole fraction formula for a solution with containing one or more solutes is: Mole fraction of each solute = Number of moles of that solute divided by the total number of moles of all solutes and the solvent.

**How do you calculate mole fraction from molarity?**

Calculate the mole fraction of solute by dividing the moles of solute by the total number of moles of substances present in solution. Calculate the molarity of the solution: moles of solute per liter of solution.

### What is the mole fraction of pure water?

Ans: Mole fraction of water is 0.71 and the mole fraction of ethanol is 0.29.

### How many moles of water are there in one liter of water?

55.56 mol

The density of water is 1g/cc, so if you do dimensional analysis, you can find that in 1 L of water, there is 55.56 mol.

**How do you calculate the mole fraction of sugar and water?**

Calculate the mole fractions of sugar and water. Solution: 1) Molality is moles solute / kg of solvent. Therefore we know our solution is: 1.62 mol C12H22O11 1.00 kg = 1000 g of water 2) Calculate the moles of water present: 1000 g / 18.0152 g/mol = 55.50868 mol 3) Determine the mole fraction of the sugar:

## How many atoms are in a mole of C12H22O11?

For every molecule of C12H22O11, there are 12 carbon atoms, aka 1:12. This means that 0.1 mole C12H22O11 is 12*0.1=1.2 mole carbon. One mole is around 6.022 * 10^23 atoms.

## How to calculate the mole fraction of NaCl in H2O?

Solution: 100.0 g / 18.0 g mol¯1= 5.56 mol of H2O Add that to the 0.100 mol of NaCl = 5.56 + 0.100 = 5.66 mol total Mole fraction of NaCl = 0.100 mol / 5.66 mol = 0.018

**How to calculate the molality of the solution?**

Solution: 1) Molality is moles solute / kg of solvent. Therefore we know our solution is: 1.62 mol C12H22O11 1.00 kg = 1000 g of water 2) Calculate the moles of water present: 1000 g / 18.0152 g/mol = 55.50868 mol 3) Determine the mole fraction of the sugar: 1.62 mol / (1.62 mol + 55.50868 mol) = 0.028357 = 0.0284 (to three SF)
