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 mass of 2 mole of water?

One mole of H2 O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

## How many grams of water is in a mole?

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 grams are in 2.00 moles?

2.00 mol Ne has a mass of 40.4 g .

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

There are therefore 6.02 × 10 ^{23} water molecules in a mole of water molecules.

## How many grams are in 3 moles of H2O?

Clearly, that is 54g. One mole of any substance is equal to its molar mass. 3 moles of water has a mass of 30g. similarly 1 mole of water is equivalent to molecular mass of water x 3 that is 18×3=54 gram.

## What does 1 mole of water look like?

Thus, for example, one mole of water (H_{2}O) contains 6.02214076×10^{23} molecules, whose total mass is about 18.015 grams and the mean mass of one molecule of water is about 18.015 daltons, roughly a combined atomic mass number of 18.

## How many grams of H2O are there in 2.50 mol of H2O?

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles H2O, or 18.01528 grams.

## How many grams is in a mole?

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 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. Sulfuric acid has the chemical formula H2SO4.
