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.
3.14
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
