Question

Number of atoms present in 0.2 g molecule of
H2SO4 is (Na represents Avogadro's number)
(1) 1.4
(2) 1.4 NA
(3) 2.8
(4) 2.8 NA​

Answer 1

Answer:

So now, since in 1 mole of Sulphuric acid, there are 2 mole of Hydrogen atoms. Hence, in 0.2 moles of Sulphuric acid, the number of Hydrogen atoms = 2×0.2 moles = 2×0.2×6×1023 = 2.4×1023atoms. Hence the required answer is, Number of H-atoms = 2.4×1023atoms.
