Please remember the Avogadro’s Number which states that 1 mole of a substance (water in your case) contains 6.023 x 10^23 molecules. Therefore, if you have 5.2 moles of water, naturally you will have (5.2 moles x 6.023 x 10^23 water molecules/ mole) = 3.1 x10^24 water molecules.

## How many molecules are present in 2.5 moles of water H2O?

1.5×1024 molecules.

## How many molecules are there in 5 moles of H2O?

There are 6.022×10^23 water molecules per mole. To calculate for 5 moles, (2 H atom)/(H2O molecule) X (6.022×10^23 H2O molecules)/(mole) X 5 moles = 6.022×10^24.

## How many water molecules are in a mole of water?

6.022 x 1023 water molecules represent one mole of water.

## How many water molecules are in 2.00 moles water?

The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 ^{23} water molecules in a mole of water molecules.

## What is the mass of 2.5 moles of water molecules?

Explanation: The number of molecules from moles by using Avogadro’s constant, 6.023×10²³ molecules/mol. =1.5×10²⁴ molecules is the mass of 2.5 moles of water.

## How many atoms are there in 5 molecules of water?

If we want to make 5 molecules of water, we need 10 hydrogen atoms and 5 oxygen atoms. The ratio of atoms we will need to make any number of water molecules is the same: 2 hydrogen atoms to 1 oxygen atom.

## How many grams is 5 moles of water?

From this you can see that 5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water. The molar mass of water is 18 g/mol, so you would end up with 5 x 18 = 90 g of water.

## How many protons are there in 5 moles of H2O?

number of protons :-

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.

## How many water molecules are in 4.0 moles of H2O?

If you have 6.022⋅1023 molecules of water, then you can say for a fact that you have 1 mole of water. Now, you know that your sample contains 4.0 moles of water. In order to find the number of molecules of water it contains, you can use Avogadro’s constant as a conversion factor.

## How many molecules are in 3 moles of water molecules?

So, in 3 moles of the substance, there’ll be 3⋅6=18 moles of water molecules. Remember that a mole of molecules contains 6.02⋅1023 molecules. So here, there’ll be a total of 6.02⋅1023⋅18≈1.08⋅1025 water molecules.

## How many molecules of water are in 100ml of water?

Which is 3.34×10^23 molecules of water are produced from 100 grams of water.

## How many molecules are there in 0.5 moles of water?

Answer: A mole is about 6.022 * 10^23 of anything. So half a mole of water molecules is 3.011 * 10^23 molecules of water. 0.5 x 6.022 x 10^23 molecules of water.

## How many H2O molecules are in 10 moles of water?

= 6.022×1024 individual water molecules.
