The charge of a nucleus is neutral, meaning it’s zero
the positive charges of an atom equal the negative charges so the atom has a neutral charge
You take 80 g of Neon times 1 mol over the molar mass, 20.18 g/mol and multiply by Avogadro's number.
T'belongs to the hydrides, it's a nitrogen hydride.
I'm assuming you need to know the percentage yield of the reaction
To calculate the percentage yield = (actual yield x 100%) / predicted yield
actual yield is 56,9 g
predicted yield is 36,6g ( is the amount that's expected if nothing had got lost)
(56,9 x100)/36,6=
= 155%
