The mass number of an atom : 26
<h3>Further explanation</h3>
Given
12 protons, 14 neutrons, and 12 electrons
Required
The mass number
Solution
Inside the atom there are 3 sub-particles, namely protons, neutrons and electrons. Protons and electrons are present in the atomic nucleus while electrons move around the atomic nucleus through energy levels in the atomic shell
Atomic number = number of protons = number of electrons
Mass number = number of protons + number of neutrons
Input the value :
Mass number = 12 + 14
Mass number = 26

<span>We know that an ideal gas keeps the relation between pressure, volume and temperature constant.
P * V / T = constant
Then if we have the gas in two diferente state:
P1*V1/T1 = P2*V2/T2
Temperature remain constant so then:
P1*V1 = P2*V2
98.5*285 = 94.2*V2
V2 = 98.5*285/94.2 = 298 ml
So the volume of the ammonia will be 298 ml</span>
