Question

How many oxygen atom are present in 9.8g of H2SO4​

Answer 1

$\mathfrak{ANSWER :- \: }$

• Total molecular weight of sulfuric acid =98

• Therefore number of moles in 9.8 gm of H2SO4=9. 8/98 = 0.1 moles

• If one mole contains 6. 023*1023 molecules, o mole would have 0. 6023*1023 molecules

• Number of Hydrogen atoms in 0.1 mole= 2*6.023*1022

• Number of sulfur atoms=6.023*1022

• Number of oxygen atoms=24.092* 1022
