H = 10 moles = 10×An = 10×6.022×10²³ = 6.022×10²4 atoms. And of O = 5×6.022×10²³ = 3.011×10²4 atoms.
How many atoms are in a mole of water?
one mole of water contains 6.02 x 1023 MOLECULES of water.
But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.
What is the mass of 5.0 moles of water?
From this you can see that 5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water. The molar mass of water is 18 g/mol, so you would end up with 5 x 18 = 90 g of water.
How many atoms are there in the 5.0 g of water?
Water consists of two hydrogen atoms connected to one oxygen atom, therefore molecular mass of water (M) is equal to sum of molecular masses of oxygen and two hydrogen atoms which is 2×1. 01 +15.99. Therefore molecular mass of water (M) is equal to 18,01. So in 5g sample of water there is 1.67 x 1023 water molecules.
What is the 5 mole of H2O?
Answer: 90 g. Explanation: Mass of one mole of water: 2 + 16 = 18g/mol. Now, mass of 5 moles = 5 x 18 = 90g.
How many atoms are in H2O?
Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H2O.
How many atoms are there 2 moles of water?
1 mole = 6.022×10^23 atoms. 1 water molecule = 2 Hydrogen atoms + 1 oxygen atom. So, 1 mole H2O = 1.2044×10^24 hydrogen atoms. Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms.
How many moles of H2O are produced using 5 moles of O2?
So, for 1 mol of O2 you get 2 moles of H2O thus 5 moles of O2 will yield 10 moles of H2O.
What is the mole of 0.5 mole of water?
Mass of 0.5 mole of water is 9g.
How many moles of water are produced when 5.00 moles of oxygen are consumed?
How many moles of water are produced when 5.00 moles of oxygen are used? Answer: 10.0 mol of water (H2O) are produced.
How many moles are in 4.5 g water?
i.e., 0.25 moles of H2O are there in 4.5 g of water.
How many water molecules are in 5 grams of 1 teaspoon water?
The number of molecules in a teaspoon of water is (5g/18.02g) x 6.022×10^23 or 1.670921198668 x 10^23 molecules. Now water consists of 2 atoms of hydrogen and 1 atom of oxygen.
What are moles of atoms?
A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
What is the mass of 5 moles of ammonia?
Mass of ammonia = number of moles × gram-molecular mass = 5×17g=85g 5 × 17 g = 85 g .
How many grams are in 5 moles?
Therefore, 160 g of oxygen is present in 5 moles.
How many grams of H2O are present in 0.5 moles of water?
(Atomic masses : H = 1 u, O = 16 u) Thus, the mass of 1 mole of water is 18 grams. Thus, the mass of 0.5 mole of water (H2O) is 9 grams.
