Mass of Hydrogen atoms : 18 g

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

$\tt (1)/(36.5)* 73=2~g$

mass H in HCl :

$\tt (2)/(18)* 144=16~g$

total mass = 2 g+ 16 g = 18 g
