The water has a molecular weight of 18. 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 are in 1 kg of H2O?

Thus 1 kg of water or ice has 55.55 moles of H20.

## How many moles are in 500g of water?

So one mole of water has a mass of 18 g. A liter is defined as the volume of 1 kg of water at standard temperature and pressure. 1 mL is thus the volume of 1 g, and 0.5 L is 500 mL or 500 g of water. Giver that 1 mole of water is 18 g, then 500 g of water must be 500 g / 18 g = 27.78 moles.

## What is the molarity of 1 kg of water?

Thus, 1000 ml of water = 1 kg. Now, Mass of Water = 1 kg. = 1000 g. Molecular mass of the water molecules = 18 grams.

## How many moles are in 1 kg?

The idea here is that 1 kg-mole is equal to 103 moles.

## How many moles is 25 grams of water?

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

## How many moles are in 8 kg of oxygen?

Conclusion: 8 g of oxygen is composed of 0.5 moles.

## How many moles are in 250g of water?

Answer and Explanation: There are 13.9 mol of water in the container.

## How many moles are in 10g of water?

10/18 moles = 10/18 * 6 * 10^23 number of molecules = 3.33 * 10^23 molecules of water. Each molecule of water has 3 atoms, so the total number of atoms in 10g of water is 3*3.33*10^23 = 10^24.

## What is the mass of 5 moles of water?

Answer: Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of 90.05 g.

## What is Molality of pure water?

Molar mass of pure water = 18.0153 g/mol. Number of moles = 55.348. Weight of the solvent = 0.99707 kg. Molality = 55.348/0.99707 = 55.510 m.

## What is the molarity of 1 liter of pure water?

The standard state for a liquid is the pure liquid, so the standard state of water is pure water, whose concentration is 55.5 M (in a liter, there are 55.5 moles of water, so its concentration is 55.5 mol/L).

## What will be molarity of pure water?

So the Molarity of pure water is 55.55 M.

## How many moles of water can make 1.8 kg of water?

Since we only have 0.001 grams, that means that we have NA * (0.001/18) = 3.35*1019 molecules of water!

## What is 1 mole in grams?

You can view more details on each measurement unit: molecular weight of In or grams The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles In, or 114.818 grams.

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

Moles of a Substance and the Molecular Weight

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.
