The equation is given by;

2HCl => H² + Cl²

According to stoichiometry;

$(n \: hcl)/(2) = \frac{n \: h {}^(2) }{1}$

$nhcl = 2 * nh {}^(2)$

To produce 0.62 moles of H² gas we need,

nHCL=2×0.62=1.24 moles

Using the relation;

number of moles:Number of atoms/Avogadro's constant

We can then say;

N(numb. of atoms)=n×Na

Number of atoms=1.24×6.02×10²³

Number of atoms=7.5852×10²³ atoms
