## How many moles does ice have?

Think about **one mole** of ice. That amount of ice (one mole or 18.0 grams) needs 6.02 kilojoules of energy to melt.

## How many moles are in air?

As long as the gas is ideal, **1 mole = 22.4L**.

## How many molecules are in ice cubes?

Therefore, for a crystal of ice with N molecules there are (3/2)^{N} possible ways to arrange the water molecules. The ice cube in your drink has a volume of about 2cm^{3}, containing about **6 × 10 ^{22} molecules**.

## What is the moles of water?

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 the formula for ice?

Since, ice is a crystalline form of water, so the chemical formula of ice is the same as that of water and the chemical formula of water is **[{H_2}O].**

## Are there more molecules in ice or water?

The “stuff” (molecules) in water is **more tightly packed than in ice**, so water has greater density than ice. … So, ice has more volume (it takes up more space, but has less density) than water.

## How many moles are in a room?

The volume of the room is therfore 8 x 10 x 3 = 240 cubic metres (m^3) – which, if the classroom is empty, is all air. There are 1000 dm^3 in 1 m^3, so our room has 240 x 1,000 = 240,000 dm^3 of air in it. Therefore, it was 240,000 / 24 = **10,000 moles** of air in it.

## How many moles are in a liter of water?

There are **55.55 moles** per litre of water .
