It depends on how many hydrogens are there and how many oxygen atoms there are.
Since there are 10 water molecules with this species there are 20 atoms of H.
4 H-atoms r in Methanol
The molecular formula H₄ indicates the presence of four hydrogen atoms. Therefore, in H₄, there are exactly four atoms in total, all of which are hydrogen.
4,2.10e25 H atoms
There are two kinds of atoms. those are N and H atoms.
1 g hydrogen (H) has 6,022 140 857.10e23 atoms.
593 g H2O x 1 mol/18 g x 2 mole H/mole H2O x6.02x10^23 H atoms/mole H = 4x10^25 atoms of H
There are 27 hydrogen atoms in retinol (C₢₂₀H₃₀O).
NH4C2H3O2 has a total of 15 atoms (1 N atom, 4 H atoms, 2 C atoms, and 8 O atoms).
divide the mass of the hydrogen by the molar mass.
1 fomula unit of KOH has 3 atoms: 1 potassium (K), 1 oxygen (O), and 1 hydrogen (H).
