The mass law is LAW OF CONSERVATION OF MASS.
The law of conservation of mass states that mass, in an isolated system is neither created nor destroy by chemical reaction or physical transformations.
This implies that, the mass of the chemicals before the reaction will be equal to the mass of the product after the reaction.
The theobromine molecule contains a total of 22 bonds
MW of gas : 124.12 g/mol
<h3>Further explanation </h3>
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of density
The unit of density can be expressed in g/cm³ or kg/m³
Density formula:

ρ = density
m = mass
v = volume
glass vessel wieight = 50 g
glass vessel + liquid = 148 ⇒ liquid = 148 - 50 =98 g
volume of glass vessel :

An ideal gas :
m = 50.5 - 50 = 0.5 g
P = 760 mmHg = 1 atm
T = 300 K
