# Best answer: How many moles are in a kg?

Contents

The idea here is that 1 kg-mole is equal to 103 moles. This is the case because a mole of a substance must contain a number of particles of that substance equal to the number of atoms present in exactly 12 g of carbon-12.

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

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

## How do you convert g mol to KG?

1 g/mol = 0.001 kg/mol – Measurement calculator that can be used to convert g/mol to kg/mol, among others.

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

In the one-kilogram iron weight there are 1.08·1025 atoms, which corresponds to the chemical amount of approximately 17.9 moles of atoms.

## 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 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 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.

## How many moles does water have?

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.

## 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 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).

Avogadro’s number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 1023. … The units may be electrons, atoms, ions, or molecules, depending on the nature of the substance and the character of the reaction (if any).

## How do you calculate Kmol?

2) Recognize that a mole is a number of grams equal to that molecular weight, or a kilomole is that number of kilograms. For example, oxygen, specifically O2 has a a molecular weight of about 32 u (using rounded numbers), so 32 g = 1 mol, or 32 kg = 1 kmol.

## How many atoms are in 2 moles of iron?

Multiply the moles Fe by 6.022×1023 atoms/mol.

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

The atomic mass of iron (Fe) is 55.85 amu. The atomic mass of radium (Ra) is 226 amu. One mole of atoms of any element contains 6.022 X 1023 atoms, regardless of the type of element. The mass of one mole of an element depends on what that element is, and is equal to the atom mass of that element in grams.
