Answer:
mass number = protons + neutrons.
Explanation:
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

All organic compounds must contain the element, Carbon.
119.37 g/mol
<h3>Further explanation</h3>
Relative atomic mass (Ar) and relative molecular mass / molar mass (M)
the molar mass/molecular mass of a compound : the sum of the relative atomic mass (Ar) of the constituent atoms
M AxBy = (x.Ar A + y. Ar B)
Atomic weight (Ar) of :
- C : 12.0107 g/mol
- H : 1.00784 g/mol
- Cl : 35.453 g/mol
The molar mass of CHCl₃

TRUE. (Lorenzo Romano Amadeo Carlo Avogadro) Ideal Gas Law that defined as one in which all collisions between atoms or molecules are perfectly elastic in which there are no intermolecular attractive forces. In such a gas, all the internal energy is the form of kinetic energy and any change in internal energy is accompanied by a change in temperature. That characterized by three state variables: absolute pressure (P) = 1 atm, volume (V) = 22.4 L and absolute temperature (T) = 273 K.
