Question

Find the moles of oxygen atom in 98g of H2so4​

Answer 1

Answer:

Explanation:

molecular mass of H2SO4 = 98g

that is 98 g of H2SO4 = 1 MOL

IN H2SO4 THERE ARE FOUR OXYGEN ATOM

NO.OF MOLES  (CONSISTING FOUR OXYGEN ATOM)= (4×16)/16=4 MOLS

THUS IN 98 g there are 4 moles of oxygen atom

GAM OF OXYGEN = 16g

Answer 2

TOTAL MASS OF H2SO4=2+32+4(16)=98

NO. OF MOLES OF H2SO4=98/98=1 MOLE IN 98g

NO OF MOLES OF OXYGEN ATOM =64/16=4MOLES OF OXYGEN ATOM
