You can work it out yourself using the equation:

e = mc2

I'm not going to do your homework for you.........

E = mc^2 c= 3*10^8 m/sso
6*10^6=m*(3*10^8)^2 =9*10^16
so m
= 6/9 *10^-10 = 6.7*10^-11 (D) kg

Remember E = m.C^2 So:
6.10^6 = m.(3.10^8)^2 Divide both sides by "(3.10^8)^2"

m = 6.10^6 / (3.10^8)^2
= 6.67.10^-11Kg
