# How many moles are in 9 grams of water?

## How many moles are in 9 grams of water?

Water has 18 grams per mole so 9 grams is 0.5 moles of water.

How many moles are present in 9 ml of water?

Therefore, 9 ml – 9 gm. Molar mass of water is 18 gm. Thus, 9 gm will have 0.5 moles of water.

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

Grade 12. 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 electrons are in a mole of water?

1 mole of water contains 6.023 x 10^(23) molecules of water. But each molecule of water contains 10 electrons. Thus 6.023 x 10^(23) molecules of water will contain 10 x 6.023 x 10^(23) electrons= 6.023 x 10^(24) electrons.

#### How many moles are in 8g of H2O?

4 moles
The atomic weight of hydrogen atoms is 1, but the molar mass of diatomic H2 is 2 g/mol. Therefore, 8 g of H2 is 4 moles. Therefore you will form 4 moles of water.

How many moles is mL of water?

One mole of water is about 18 milliliters. It’s not a large volume, yet it contains 6.022 x 1023 water molecules! You can use the same steps to find the mass and volume of any other substance.

## How many moles of water are present in 1 mL of water?

of moles of water in 1 ml = 1/18 mol.

How many molecules are present in 1g of water?

Answers (1) or 1 g of water contains (6.022 x 1023)/ 18 water molecules and the number comes out to be 3.3455 x 1022. So the number of water molecules present in 1 g of water is 3.3455 x 1022.

### How many electrons are present in water?

10 electrons
The water molecule has a total of 10 protons and 10 electrons (8 from the oxygen atom and 1 from each of the two hydrogen atoms). Since it has the same number of protons and electrons, the water molecule is neutral. The electron cloud model shows where electrons are in a molecule.

What is the mass of 10 moles of water?

Number of moles=Mass/Molecular Mass. n=m/M. 10=m/18. Therefore,Mass of 10 moles of water =10×18=180 g.

#### How many molecules are there in 9g of water?

So 9g of water will be half of a mole. 1 mole of any substance contains 6 X 10 ^ 23 molecules. So half a mole will have about 3 X 10 ^23 molecules . Each molecule of water has ( 8 + 1+1) 10 electrons. So the total number of electrons will be 10 * 3 *10^24 = 3 X 10 ^ 24 electrons…. 1 mole of Water has 6.022 × 10 23 molecules.

How many moles of electrons are there in 9 grams of water?
