## How do you calculate 1 mole of NaCl?

One mole of sodium (Na) is 22.99 g, and 1 mole of chlorine is 35.45 g. For sodium chloride (NaCl) they are in a ratio of 1:1 so the molar mass of NaCl is 22.99 + 35.45 = 58.44 g/mol.

## What is the 1 mole of NaCl?

Skill 3-1 Calculate the molecular mass of a compound as the sum of the atomic masses of its elements. So, one mole of water (6.022 x 10 23 molecules) has a mass of 18.02 g. One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g. Concept 2.

What is the 5 mole of h2o?

Explanation: Mass of one mole of water: 2 + 16 = 18g/mol. Now, mass of 5 moles = 5 x 18 = 90g.

### How many moles are in 1 mole of h2o?

Mass of 1 Mole of Water A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms. From the periodic table we see the atomic weight of hydrogen is 1.0079 and the atomic weight of oxygen is 15.9994. Atomic mass is the number of grams per mole of the element.

### What is the weight of 1 mole?

Thus, for example, one mole of water (H2O) contains 6.02214076×1023 molecules, whose total mass is about 18.015 grams and the mean mass of one molecule of water is about 18.015 daltons….Mole (unit)

What is 0.5 mole water?

Mass of 0.5 mole of water is 9g.

## How many grams are in 5.0 moles of H2O?

From this you can see that 5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water. The molar mass of water is 18 g/mol, so you would end up with 5 x 18 = 90 g of water.

## What is 1 mole of water equal to?

The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.

Which is the mole fraction of NaCl in water?

The mole fraction of NaCl , in a solution containing 1 mole of NaCl in 1000 g of water is: 12th.

### How to calculate the molar mass of sodium chloride?

Calculate its molar mass. For sodium chloride it’s equal to 58.44 g/mol (as Na = 22.99 g/mol and Cl = 35.45 g/mol). Convert grams to moles. Use the formula moles = mass of solute / molar mass.

### How to calculate the mole fraction of aqueous solution?

Example #4:The molality of an aqueous solution of sugar (C12H22O11) is 1.62 m. 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

How to calculate the molality of a gram of salt?

Convert grams to moles. Use the formula moles = mass of solute / molar mass. Assume we want to dissolve 70.128 grams of salt in 1.5 kg of water. so moles NaCl = 70.128 g / (58.44 g/mol) = 1.2 mol. Plug moles value and the mass of the solvent into the molality formula.
