## What is 1kg mole?

The kilogram-molecuIe (kilomole) is the mass of a substance which is expressed in kilograms and is numeri- cally equal to the molecular mass of the substance. For instance, the kilomole of water is 18 kg, that of oxygen 1% 2 is 32 kg, etc.

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

Now 18g of H20 is equivalent to 1 mole. Hence, 1000g of it would be equal to 1000/18 moles. This comes out be 55.55 moles. Thus 1 kg of water or ice has 55.55 moles of H20.

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

6. 023×1023 moles.

## 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 moles are in 1 kg of oxygen?

so,62.5 moles of oxygen have (6.022×10^23×62.5) molecules. Hence 1 kg of oxygen has (376.38×10^23) molecules.

## How much is a mole?

A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
