Question

Gram atom of H in 98g of sulphuric acid

Answer 1

Answer:

Explanation:

1 mole H2SO4 forms 1 mole Hydrogen atom

Mass of H2SO4 = 294g

Molar mass of H2SO4 = 1×2 + 32 + 16×4

Molar mass of H2SO4 = 34 + 64

Molar mass of H2SO4 = 98 g/mol

Moles of H2SO4 =mass /molar mass

Moles of H2SO4 = 294/98

Moles of H2SO4 =3mol

So 3 mole will produce 3 mole hydrogen atom

1mole = 6.023×10^23

So 3 mole hydrogen atom = 3×6.023×10^23

Number of hydrogen atoms = 18.069 ×10^23
