mass of water = 5.0 moles x 18 g/mol = 90 grams.
What is the mass of 2 moles of H2O?
One mole of H2O 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.
How many grams are in 2.5 moles of h20?
Explanation: The amount of oxygen in 2.5 moles of water is 40 grams. The molecular formula of water is H₂O. 1 mole of water contains 1 mole of oxygen.
What is the mass of 2.5 moles of water?
Mass of 2.5 moles H2O = 2.5*18 = 45 g.
What is the mass of 5 moles of H2O?
5 mole of water =0. 5×18 =9gm. Was this answer helpful?
How many grams are in 1 mole of H2O?
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 molecules are in 2 moles of CO2?
Thus, if we have 1 mole of a molecule present, we have 6.022*10^23 of those molecules present. If we have 2 moles of a molecule present, we have 2*1.022*10^23 of that molecule present etc.
How many grams are in 10 moles of H2O?
›› More information from the unit converter
