How many molecules is 3 moles?
A mole of anything contains 6.022×1023 individual items of that something. You have 3 moles, so there are 3×6.022×1023 oxygen molecules .
What is the mass of 2 moles 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.
What is the mass of 5 moles H2O?
Five moles of water whould have a mass of 90.05 g.
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.
How many atoms are in 3 moles of water?
Calculate the number of gram atoms in 100 ml mercury. Given: Density of Hg=13. 6 g ml−1 and molar mass of Hg=200 g mol−1.
What is 3 moles O2?
3 moles of Oxygen atoms weigh 48.00 grams.
How many grams is 2.5 moles of water?
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 3 moles of carbon dioxide?
Explanation: Carbon dioxide has a molar mass of 44.01⋅g⋅mol−1 …and so for the mass of a three quantity we take the product… 3⋅mol×44.01⋅g⋅mol−1≡?? ⋅g …and in this quantity how many moles of carbon, and how moles of oxygen?
