Question

Calculate the mass percentage of Hydrogen in sulfuric acid H2SO4​

Answer 1

Explanation:

mass% of an element

=mass of the elements in the compound × 100

/molar mass of the compound

molar mass of H2So4= 2+32+4(16)

" = 98g/mol

mass percent of hydrogen= 1×100/ 98

" = 1.02%

mass percent of sulfuric = 32×100/98

". = 32.65%

mass percent of oxygen = 64×100/ 98

". = 65.30%
