Question

10. How many atoms of oxygen is present in 196gm of H2SO,? Given atomic mass of
H=1, S=32,0=16​

Answer 1

Answer:

don't you didn't talk about that at all in my

Answer 2

Answer:

Given :-

molecular mass of H2SO4 = 2*1 + 32 + 16*4 = 98

To find :-

no. of atoms in 196 gm H2SO4

Solution:-

moles of H2SO4 = mass / molecular mass

= 196 / 98

= 2

1 molecule of H2SO4 contain 4 oxygen atom

1 mole of H2SO4 will have 4 mole oxygen atom

Total oxygen atom = 4*6.022 * 10^23
