The binding energy of Mg-24 is 198MeV. What is this value in Joules? Write your answer correct to three significant figures.

MeV = megaelectron volt

1 megaelectron volt = 1.60217646 × 10-13 joules

198 megaelectron volts = 3.17230939 × 10^-11 joules

198 megaelectron volts = 3.17230939 × 10^-11 joules

So, the answer should be3.17E-11. Correct?

I got the answer wrong on the homework... Could it be because I didn't add the unit to the end of the answer?

Or am I just completely wrong?
