Question

calculate no. of moles, molecules and atoms in 196g of H2SO4​

Answer 1

Answer:

no of moles= given mass/ molar mass

196/98

Answer 2

H2SO4

1*2+32+16*4

"2+32+64 ..98

the 98 of sulphur =1mole

so the no of moles 196of H2SO4 is 2 mole answer

molecules we know Avargardo no 6.o22*10°23

so

2*6.022*10°23

=12.044*10°23 is answer

atoms=mass of 1mole of H2SO4=98 amu

the molecule=2

thus the number of atom =2*7=14
