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.
