How many grams is 18 moles water?
– We can say that 18 grams of water means same as 1 mole of water , and in this NA Avogadro number of water molecules are present , which means 6.02×1023 molecules.
How many water molecules are there in 18 ml water?
Answer: So 18 ml of water weights 18 gm. So it contain 6.022*10^23 molecules ie avagadro number of molecules.
How many moles is 18 grams?
It is equal to Avogadro’s number (NA), namely 6.022 x1023. If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 molesof H atoms) + 16 grams (for one moleO atom) = 18 grams.
How many moles are in 20.00 grams of water?
Hence,number of moles in 20g of water is 1.11111……
What is a mole of H2O?
H2O Average atomic mass of H: 1.01 g/mol. Average atomic mass of O: 16.00 g/mol. 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.
What is the mass of 5 Moles H2O?
Five moles of water whould have a mass of 90.05 g.
How do you find mass of water?
Explanation: 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.
