Explanation:
The formula for sulphuric acid is [tex]H_{2}SO_{4}[/tex].
Molecular mass of sulphuric acid is [tex]2(2)+32+16(4)=98g[/tex]
[tex]given weight=98g[/tex]
Number of moles of sulphuric acid given is [tex]\frac{\text{given weight}}{molar mass}[/tex]=[tex]\frac{98}{98}=1[/tex]
The formula indicates that one mole of [tex]H_{2}SO_{4}[/tex] contains [tex]2[/tex] moles of [tex]H[/tex] atoms,[tex]1[/tex] mole of [tex]S[/tex] atoms,[tex]4[/tex] moles of [tex]O[/tex] atoms.
So,the compound contains [tex]1[/tex] mole of sulphur atoms.
[tex]1[/tex] mole of sulphur has [tex]6.022\times 10^{23}[/tex] atoms
