I was doing some chemistry problems when I came across a question asking to find the charge to mass ratio of an electron in $q/m_e$. Then, it told me to compare what I found to the accepted value, at $1.76 x 10^{11} C/kg$ and calculate my percent of error. How do I convert the two?

I am a beginner to chemistry and physics. so please don't provide advanced answers.

The thing is, this is a really elementary question. Not just in the sense of the concepts involved being simple (which is fine), but also in the sense that it requires almost no work, which suggest that perhaps you haven't given it a fair chance yourself. Did you try looking up the known values of $q$ and $m_e$? Did you run into a problem when doing so? – David Zaslavsky♦ Sep 16 '12 at 3:33

Given David's comment, voted to close as too localized. When you ask "I am asked to compute A divided by B" and you know A and you know B, I don't know any reasonable way to help. – Ron Maimon Sep 16 '12 at 7:54
Probably you are confusing it with unit conversion problem, which it is not. Its rather like computing ratio height/weight of a given person. If you know height of the person in (say) centimeters, and weight in kilograms then you can express your answer for height/weight in terms of centimeter/kilogram (e.g. if height = 150 cm, weight = 50 kg, then height/weight = 3 cm/kg ). – user10001 Sep 17 '12 at 0:15
yeah, ok I understand now. thanks. – Chase Yuan Sep 17 '12 at 20:45
