Question

O.25 moles of SO₂ will contain

Answer 1

Explanation:

number of mole s of H

2

= 0.25 moles

number of molecules = moles * Avogadro’s Number

number of molecules = 0.25×(6.022×10

23

)

number of molecules = 1.505×10

23

single molecule of hydrogen contains two H-atoms. So,

number of atoms = 2×(1.505×10

23

) = 3.01×10
