Answer:
A sodium atom.
Explanation:
A sodium atom contains 11 protons and 12 neutrons and its mass is 23.
Quadruple
Since we double both P and V in the numerator, the denominator (T) has to be doubled twice, or quadrupled (multiplied by 4)
Example:
P1 = 5
V1 = 2
T1 = 10
5*2/10 = 1
P2 = 5*2 = 10
V2 = 2*2 = 4
T2 = 10*4 = 40
10*4/40 = 40
