# Frequent question: How many moles of water are in a kilogram?

Contents

## How many moles are in 1 kg?

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 molecules of water are present in 1kg of water?

By mole concept, we know that 1 mole molecule of any substance has avogadro number of molecules(6.022*10^23). So we need to find the moles ofwater in 1 L of water or 1000mL of water. Taking the density of water to be 1g/mL, 1000mL of water= 1000g water. hope it helps you. . .

## How many grams of water are in 1 mole of water?

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.

## What is 1kg mole?

Alternatively, a (kilogram mole) is equal to gram moles, and therefore can be thought of as having times 6.022 140 × 10 23 particles.

## 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. I HOPE THAT IT WILL HELP YOU. PLEASE MARK THIS ANSWER BRAINLIEST.

## What is 1 mole in grams?

Another property of Avogadro’s number is that 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 water molecules are in 2 liters of water?

0.08929 moles H2O x 6.02×1023 molecules/mol = 5.4×1022 molecules = 5×1022 molecules (1 sig.

## How many molecules are in a kilogram?

If a molecule weighs X amu, then a mass of it that weighs X grams has 6.022×10^23 molecules in it. This last number is called Avagadro’s number and is familiar to any high school chemistry student. So 1g = 6.022×10^23 amu. Therefore 1 kg = 6.022×10^26 amu.

## How many molecules are in 1l of water?

One mole of water has a mass of 18 grams and a volume of 18 mL (as the density of water is 1 g per cm3). It contains Avogadro’s number of molecules (6x 10^23). Thus 1 litre of water contains 1 / 18 x 1000 x 6 x 1^23. molecules……

## How many moles is 25 grams of water?

Hence, 1.38 moles (mol) are present in 25 grams of water.

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

One mole of water has a mass of 18 grams and volume of 18 milliliters or 0.018 liters. How much is a mole of water? A mole of water is Avogadro’s number of water molecules.

THIS MEANING:  What is the mass of 2 5 moles of NaCl?
