Mass of electron = 9.109 X 10-28 g
Hence,
begin mathsize 12px style fraction numerator Mass space of space proton over denominator Mass space of space electron end fraction equals fraction numerator 1 comma 673 space cross times space 10 to the power of negative 24 space end exponent straight g over denominator space 9.109 space cross times space 10 to the power of negative 28 end exponent space straight g end fraction equals 1837 space end style
