## How many moles are there in 9g of H2O?

= **0.5 Moles** of H2O .

## How many moles is 10 grams of water?

1 mole of water weighs 18g. 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**.

## How many particles of water are found in 9g of water?

= **3.** **011 x 10^23**.

## How many atoms are in 9g of water?

9 is 1/2 of 18, meaning that 1/2 mole is present in 9 g of water. 1/2 * 6.022 *10^23 = 3.011 * 10^23 molecules H2O. However, if you want to know how many ATOMS are present in 3.011 *10^23, you must then multiply by 3 (2 hydrogen atoms and 1 oxygen atom per molecule), and get **9.033 * 10^23 atoms**.

## How many moles of H2O are present in 10 grams of water?

=>Molar mass of H2O = 18 g mol-1. 18 g of H2O contains = 6.022×1023 molecules. 10 g of H2O cotains =6.022×102318×10 = **3.34**×1023 molecules.

## How many moles are present in 10 grams of H2O?

**One mole** of any substance weighs about the same as the molecular mass of that substance. Hence, there are [3.34times {10^{23}}] molecules of [{H_2}O] present in a 10 gram sample of [{H_2}O] .

## How do you find moles of water?

As in the given question we have to calculate how many moles are present in the 25 grams of water and for this we have to **divide the given weight of water by the molecular weight / mass of water**. Hence, 1.38 moles (mol) are present in 25 grams of water.

## 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 5 grams of water?

**5/18 moles** for 5 grams of water.
