Question

How many molecules are in 2.00 moles of H2O?​

Answer 1

Answer:

of atoms (molecules )÷ avogadro no. Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water. Double that for 2 moles, and there are 24.088 x 10^23 hydrogen atoms in one mole of water.

Hope it helps you!! :)

Answer 2

Answer:

2 mole H2O will have 2.4088×10^24 hydrogen atoms.

Explanation:

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.

Molecules 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.
