Given the following information: Red giants derive their energy not from nuclear fusion of hydrogen, but by fusion of helium. Specifically, a reaction where 3 helium nuclei fuse into 1 carbon nucleus. The mass of a helium nucleus is 6.645x10-27 kg, and the mass of a carbon nucleus is 1.9922x10-26 kg
The mass-energy relation is famously: E = mc2

1) What is the mass of the three helium nuclei? That is: what is 3mHe = ?

Enter your answer in kilograms.

Submit your answer as the coefficient (Y) of the below scientific notation expression:

Y x 10-27 kg
