HELP MEPLEASE SOMEONE REALLY REALLY REALLY SMART PLEASE What is the mass of an atom with seven protons, seven neutrons, and eight electrons?
EXPLAIN:

Explanation: The atom is a nitrogen atom  and the mass of the atom is 14.0067 u.

one state would change   like louisiana to texas. thats a change

explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
