## What is 2 moles H2O?

H has mass 1 and oxygen has an atomic mass of 16. … One mole of water has a molecular mass of 18 grams. Two moles of water have a molecular mass of 18×2=36 grams. Thus the molecular mass of two moles of water is 36 grams.

## What is the weight of 2 moles of water?

weight of water = 2(1.0079) g + 15.9994 g. weight of water = 2.0158 g + 15.9994 g. weight of water = 18.0152 g.

## What is the moles of water?

One mole of water is about 18 milliliters.

This is the volume of a few drops of water, 3.65 teaspoons, 1.2 tablespoons, or 0.018 liters. It’s not a large volume, yet it contains 6.022 x 10^{23} water molecules! You can use the same steps to find the mass and volume of any other substance.

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

›› More information from the unit converter

The answer is 18.01528. We assume you are converting between grams H2O and mole.

## How many atoms are in 2 moles water?

1: Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.

## How many moles of water is 74.5 grams of water?

We’ll convert given 75g H2O into moles of H2O,which’ll give us number of molecules via the use Avogadro’s number. ➡75g(or 4.16mol) of H2O=25.08×10^23 molecules(approx.)

## 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.

## What is moles to grams?

The amount of grams in a mole depends on the substance you have. To work it out, find the atomic or molecular mass of your substance and multiply it by the number of moles you have. For one mole, the atomic or molecular mass will be the same as the weight.

## How many moles of water are there in 100g of H2O?

There are approximately 5.55 moles of water in a 100-gram sample of water.
