How many grams is 12 moles of water?

How many grams of water are 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 do you convert moles of water to grams?

To get from moles to grams you need to use the molar mass which is the weight in grams of one mole (g/mol).

For water ( H2O ) take the sum of the molar masses of 2 hydrogen and 1 oxygen atom:

  1. Hydrogen ( H ) = 1.008 g/mol ⋅2=2.016 g/mol.
  2. Oxygen ( O ) = 15.999 g/mol.
  3. Molar mass of H2O = 2.016+15.999=18.015 g/mol.

What is the mole of 20g of water?

Hence,number of moles in 20g of water is 1.11111……

What does 1 mole of water look like?

Thus, for example, one mole of water (H2O) contains 6.02214076×1023 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 would 10 moles of water weigh?

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 grams is 5 moles of water?

Answer: Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of 90.05 g.

How many liters are in 1 mole of h2o?

For water, 1 mole = 18 g= 22.4 liter.
