Question

how many megaculomb of positive charge are present in 2.0 mole of neutral hydrogen gas ?

Answer 1

Number of molecules in 2.0moles of H2 gas=2.0*6.02*10^23 As each H2 molecules contains 2 electrons/protons ,so n=2*2.0*6.02*10^23=24.08*10^23 q=ne=24.08*10^23*1.6*10^-19 =0.3853*10^6C = 0.3853MC


ok this is ur answer and correct answer u can check this with u teacher also
thank u
