Ilya [14]3 years ago
3 0

Answer:

24 atoms of H  or 1.4 x 10²⁵ hydrogen atoms

Explanation:

simple method

1 H₂O has  atoms of hydrogen and 1 atom of oxygen

while 12H₂O will have 24 atoms of hydrogen and 12 atom of oxygen

by Avagadros number

molar mass of water H₂0=18.01528 g/mol

1 mole of H₂0 have 2 moles of Hydrogen  

one mole of water= 6.02⋅10²³water molecules =1.2 x 10²⁴hydrogen atoms

12 mole of H₂O   =    1.2 x 10²⁴ x 12=  1.4 x 10²⁵ hydrogen atoms  

<u />

1.4 x 10²⁵ hydrogen atoms   in 12 moles of H₂O

<u />
