Mass of Hydrogen atoms : 18 g

Further explanation

Given

73 gram of HCl

144gram of H₂O

Required

Mass (gram) atom of Hydrogen

Solution

H atoms are in 2 compounds, H₂O and HCl, so we calculate their mass in each compound

  • mass H in H₂O :

[tex]\tt \dfrac{1}{36.5}\times 73=2~g[/tex]

mass H in HCl :

[tex]\tt \dfrac{2}{18}\times 144=16~g[/tex]

total mass = 2 g+ 16 g = 18 g
