Answer:

#"Multiply by Avogadro's number",N_A#

Explanation:

#N_A=6.022xx10^23*mol^-1#

And thus #4.25xx10^-2*mol# of sulphuric acid represents #4.25xx10^-3*molxxN_A=4.25xx10^-3molxx6.22xx10^23*mol^-1=2.56xx10^21# molecules of sulfuric acid. How many moles of hydrogen, and oxygen do this molar quantity represent?
