## Homework Statement

What is the rest mass energy of one mole of neutrons? Hint one mole is 6.02 x 1023 particles (avocado's number), and the neutron has mass m=1.675 x 10 -27 kg.

## Homework Equations

## The Attempt at a Solution

I wasn't sure of the relationship between moles and mass. What I attempted to do was multiply one mole by the mass. Then plugged in the equation of E=mc2. I came up with the answer of 9.075 x 10 16. This just doesn't seem right. Any help would be appreciated.
