## How many moles is 72 grams of water?

72 g of wateroccupies **4 moles**.

## How many grams of H2O are present in 0.75 mole?

And note that 0.75⋅mol H2O2 represents a mass of 0.75⋅mol×34⋅g⋅mol−1≡**25.5⋅g** ……..etc……..

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

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 moles are in 360g of water?

(ii) From point, 1 mole of water = molar mass of water =18g **20 moles** of water = 18 g x 20 = 360g (iv) From point, 6.022 x 1023 molecules of water = 1 mole = 18g of water 1.2044 x 1025 molecules of water Therefore, points (ii) and (iv) represent 360 g of water.

## What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to **multiply the mole value of the substance by its molar mass**.

## How do I calculate moles?

**How to find moles?**

- Measure the weight of your substance.
- Use a periodic table to find its atomic or molecular mass.
- Divide the weight by the atomic or molecular mass.
- Check your results with Omni Calculator.

## How many grams are there in 1.50 moles of water?

Conclusion: Thus it can be inferred that the mass of 1.5 moles of water is **27g**.

## How many grams are in 2 moles of water?

It is equal to Avogadro’s number (NA), namely 6.022 x10^{23}. If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = **18 grams**.

## How many moles of hydrogen are needed for 100 grams of water?

Unlock

1 mole of water requires 1 mole of hydrogen (H2) and 0.5 moles of oxygen (O2). This requires **100/18 moles** of hydrogen. As the molar mass of hydrogen is 2, it requires 200/18 = 100/9 g of hydrogen. It requires 100/9 g of hydrogen gas and 800/9 g of oxygen gas to make 100 g of water.

## What represents 360g of water?

One mole of water is equal to 18 grams of water. Therefore 360 grams of water is equal to **20 moles of** water.

## How many grams are in 2 moles of HF?

Explanation: Normally 1 mole of F2 reacts with 1 mole of H2 giving 2 moles of HF (which is **20g**).
