i have a lab, where you took a pile of m&ms and weighted them on a digital scale. and then we found the mass of just one. but i forgot what we did to find the mass of 1. we didn't just put one m&m on the scale. anyone know how to find the mass of one?

Did you count the number of candies, then divide the mass by that number?

nitrogen mass

According to the periodic table I have, but check yours if it is up to date, is 14.00864 amu per atom of nitrogen.
