## How many moles are in 1 kg of water?

Molecular mass of water(H2O) is 18gram which contains 1mole . Now, 1kg water contain 1000/18 =55.55mole .

## How many moles is 1 kg?

How many Kilogram-mole make 1 Mole? 1 Mole [mol] = 0.001 Kilogram-mole [kg-mol] – Measurement calculator that can be used to convert Mole to Kilogram-mole, among others.

## How do you find moles from KG?

It’s easier to work with grams, so convert the mass: 5.988 kg = 5988 g . As you already know how the grams to moles conversion work, find the number of moles: n = 5988 g / 18.015 g/mol = 332.4 mol .

## What is 1 mol H2O?

Mass of 1 Mole of Water

Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms. … This means 1 mole of hydrogen weighs 1.0079 grams and 1 mole of oxygen weighs 15.9994 grams.

## What is the weight of 12 moles of water?

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Water, or 18.01528 grams.

## How many moles are there in 1 Litre of water?

The liter of water has 1000 grams. The number of moles is 1000/18 = 55.556 moles. The number of molecules is therefore 6.022*1023 * 55.556 = 3.346*1025 molecules.

## What is 1 mole in grams?

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

## How many atoms are in 1kg of water?

There are 55.56 moles of water in a kilogram of water. A 55.56 moles times 3 times Avogadro’s number give the answer. 3 x 55.56×6. 022×10^23 = 1.004 x10^26 atoms per kg of water.

## How do I calculate moles?

Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.

## How many atoms are in a mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## How do you convert moles to mass?

Multiply the molecular weight by the number of moles for the substance. The molecular weight is the number of grams per mole for the substance and gives the conversion factor for moles to grams for that particular substance. So, one mole of water has a mass of 18.02 grams (1 mol H2O x 18.02 g/mol = 18.02 g).

## How do you find moles from ML?

MOLES FROM VOLUME OF PURE LIQUID OR SOLID

There are two steps: Multiply the volume by the density to get the mass. Divide the mass by the molar mass to get the number of moles.
