Mass is a fundamental quantity. It's the amount of 'stuff' that an object is made of.
You can't get it from a formula, any more than there's a formula for a person's height
or the weight of a bag full of sand. You measure it.
the fomula is p.e=Mgh where g is the acceleration due to gravity & M is the mass which is in kg & H is the height.
Use this fomula: (m/M)*NA in which m is mass in gram (g), M is molar mass (g/mol) and NA is the Avogadro number (mol^-1)
Empirical formula = C3H5O Molar mass of empirical formula = 3(12.01)+5(1.008)+1(16) = 57.07 Molar mass of molecular fomula = 114.15 n = Molar mass of molecular fomula/Molar mass of empirical formula = 114.15/57.07 n = 2 Molecular formula = n(empirical formula) Molecular formula = 2(C3H5O) = C6H10O2 Check: 6(12.01)+10(1.008)+2(16)= 114.14

Density is calculated by the formula: Density = Mass / Volume. Mass is the amount of matter in an object, measured in kilograms or grams, and volume is the amount of space an object takes up, measured in cubic meters or cubic centimeters.
