There are 23 atoms in 6.0 g of water. Using this formula (6 g H2O)(1 mol H2O / 18 g H2O) = 1/3 mol H2O (1/3 mol H2O)(2 mol H / 1 mol H2O)(6.022 x 10^23 atoms H / 1 mol H) = 4.0 x 10 therefore 23 atoms.
One atom of hydrogen, or gaseous hydrogen? Will do both and you chose the one you need
atom H
3.0 grams hydrogen (1 mole H/1.008 grams)(6.022 X 10^23/1 mole H)
= 1.8 X 10^24 atoms of hydrogen
----------------------------------------------
gaseous hydrogen H2
3.0 grams H2 (1 mole H2/2.016 grams)(6.022 X 10^23/1 mole H2)
= 9.0 X 10^23 atoms of gaseous hydrogen, H2
3.65 grams water (1 mole H2O/18.016 grams)(2 mole H/1 mole H2O)(6.022 X 10^23/1 mole H)
= 2.44 X 10^23 atoms of hydrogen
There are 3 sextillion hydrogen atoms on 0.05g of water. The amount for 3.65 is very difficult to calculate.
3.5 X avagadro's number divided by Molar Mass.
so its 3.5 x 6.02x10 to the 23rd power / 18 = 1.17x10 to the 23rd
There are 0.194 moles of water in 3.5 grams and it has 0.582 moles of atoms as every water molecule has three atoms. It is 3.51 x 1023.

No,boiling water does not have oxygen . Cold water molecules move slowly meaning there is space between the molecules for more oxygen to dissolve. Hot water molecules move rapidly meaning the space between the water molecules is less avalible for the oxygen molecues to dissolve into.
2. Because it is H2O. the 2 is after the h showing how many
A homogeneous mixture means that it is uniform throughout. Colloids are mixtures with particle sizes that consist of clumps of molecules, but cannot be separated by filtering. Fog is like a colloid because it is composed of water droplets suspended in the air. They're too small to fall like rain, but they're not H2O(g) molecules (otherwise, that would be like... air, which is a mixture). It is still H2O(l).
I'm pretty sure it's Hydrogen Bonding. :) -K.
Water is composed of may molecules each of which is made up of two hydrogen (H) atoms and one oxygen (O) atom, giving the formula H2O.
no H2O molecules are produced:)
1 mole H2O = 6.022 x 1023 molecules H2O 2mol H2O x 6.022 x 1023 molecules H2O/1mol H2O = 1 x 1024 molecules H2O

There is one water molecule in H2O
0.943 moles H2O (6.022 X 1023/1 mole H2O) = 5.68 X 1023 molecules of water ========================
The number of molecules is 2,308.10e23.
1 mole H2O = 6.022 x 1023 molecules 0.357mol H2O x 6.022 x 1023 molecules/mol = 2.15 x 1023 molecules H2O
1.08x10^22
A lot
1 mole H2O = 18.015g H2O = 6.022 x 1023 molecules H2O 1.5 x 1023 molecules H2O x 18.015g H2O/6.022 x 1023 molecules H2O = 4.5g H2O
200 grams H2O (1 mole H2O/18.016 grams)(6.022 X 1023/1 mole H2O) = 6.69 X 1024 molecules of water ======================
