I've fixed my latex errors! hopefully. Calculate the mass deficit in this nuclear reaction $12{\rm C}+\frac{12}{6}{\rm C}\rightarrow \frac{24}{12}{\rm Mg}$ Information given:  rest mass of a carbon12 nucleus: $1.9921157\times 10^{26}\,{\rm kg}$  rest mass of a magnesium nucleus: $3.9817469\times 10^{26}\,{\rm kg}$  rest mass of a proton: $1.67353\times 10^{27}\,{\rm kg}$  rest mass of a neutron: $1.67492\times 10^{27}\,{\rm kg}$  speed of light: $3.00\times 10^{8}\,{\rm m}\,{\rm s}^{1}$

I'm thinking you add two C12 and take it off mg24 If so 12.15768613.817469=1.659783 is this the answer or have I done something wrong?

1.9921157×10−2kg+1.9921157×10−26kg−3.98174 69×10−26kg=0.002484x10−26kg Is this correct ? Note in the question above they are both meant to be $12/6C$
