Question

The no.of hydrogen atoms in 0.25 mole of sulphuric acid.

Answer 1

Answer:

Hydrogen atom = 3.01×10^23

Explanation:

1 mole of H2SO4 has 2 moles of Hydrogen atoms, 1 mole of Oxigen atoms and 4 moles os Sulfur atoms

1 : 2 = 0.25 : x

x = 0.50 moles

1 mole contains 6.02 x 10^23 atoms ( Avogadro's number)

1 : 6.02 x10^23 = 0.5 : x

x = 3.01 x 10^23 Hydrogen atom
