Question

calculate the no. of atoms of constituent element in 49g of sulfuric acid (H2S04)

Answer 1

Hi,

- The molar mass of H2SO4 = (2+32+16×4)=98 g/mol

- Nuber of moles = 49÷98=0.5 mol

- no.of molecules of H2SO4 = no of moles × avogadro's no.

= 0.5×6.02×10^23 = 3.01×10^23

No of (S) atoms = 3.01×10^23

Hope the answer useful for u , good luck
