The formula mass of any molecule, formula unit, or ion is the sum of the average atomic masses of all atoms represented in its formula.
Mass = force ( weight) / acceleration due to gravity
Mass = weight /gravity Density = Mass / Volume So, if you know the density and the volume, you can calculate the mass. Also, you can measure the mass by measuring the weight. On earth, mass and weight are equal.
The formula mass for boron nitrate is 197 grams per mole.
Barium fluoride is BaF2. Its empirical formula is BaF2 as well. Hence, its formula mass is same as its molecular mass i.e.175.34g/mol
its Gram Formula Mass
The density or some other information must be given that allow you to find the molar mass. Calculate the empirical formula mass. Divide molar mass by empirical formula mass. This answer is multiplied by all subscripts of the empirical formula to get the molecular formula.
mass formula
There is no formula for mass. it is simply the weight measured in grams
relative formula mass of MgCO3
Molar mass is the mass of particles in one mole of a substance. Molar mass is equal to atomic/ molecular/ formula mass in amu. Formula mass is in atomic mass unit while molar mass is in grams .
Mass = force ( weight) / acceleration due to gravity
The formula mass of any molecule, formula unit, or ion is the sum of the average atomic masses of all atoms represented in its formula.
Mass times volume isn't a formula for anything. You may be confused with mass divided by volume, which is the formula for density.
molar mass over grams of elementThe above answer is somewhat correct. In order to find the molecular formula when given the empirical formula, you must first find the molar mass of the empirical formula.MOLAR MASS# atoms element A x Atomic Mass element A (Periodic Table) = mass A# atoms element B x atomic mass element B (periodic table) = mass B... etc.Add up all of the mass values found above and you have the molar mass.Then, after you have found the empirical formula's molar mass, you divide the molar mass of the molecular formula by the empirical formula's molar mass (solving for n).MOLECULAR FORMULA EQUATION: N (Empirical formula) (read as N times empirical formula) where:N = Molar mass substance---- Molar Mass emp. form.
The actual mass must be divided by the empirical mass. This was derived from the following equation: (subscript)(empirical formula) = (molecular formula) subscript = (molecular formula)/(empirical formula)
Mass (M) x Volume (V) is not the formula for anything. Mass multiplied by Volume is the formula for density. Mass multiplied by velocity (speed with a direction) is the formula for momentum.
