Answer:

Approx. #3xx10^25# #"electrons"#.

Explanation:

In one MOLECULE of #H_2SO_4#, there are #2xx1(H)+16(S)+4xx8(O)=50# electrons in total.

But we have a molar quantity of #(196*g)/(98.08*g*mol^-1)=2*mol#. And given that there are #"Avogadro's number,"# #6.022xx10^23*"particles mol"^-1#, we have #N_Axx50*"electrons"#

#=3xx10^25# #"electrons"#............anyway, do this on your calculator and see if I have got the arithmetic right for once.
