To find the volume of an object use the formula v=dm where Volume=Density x Mass To find the mass of an object use the formula m=dv where Mass=Density x Volume
Mass = Density -------- volume
The answer depends on the information that has been provided.
The formula for calculating density is as follows: density = mass/volume. Simply put, if you divide an object's mass by its volume, you will find its density. Density is the mass of an object per unit volume.
the formula to find specific heat is specific heat= calories/mass X change in temperature.
To find the molecular formula of a compound, you need to know its empirical formula and molar mass. Divide the molar mass of the compound by the molar mass of the empirical formula to find the "multiplication factor." Multiply the subscripts in the empirical formula by this factor to get the molecular formula.
The formula to find mass with density (ρ) and volume (V) is: mass = density × volume
To find the volume of an object use the formula v=dm where Volume=Density x Mass To find the mass of an object use the formula m=dv where Mass=Density x Volume
To find the molecular formula from the empirical formula, we need to know the molar mass of the empirical formula. In this case, the empirical formula's molar mass is 88. To find the molecular formula, we divide the given molecular mass (176) by the empirical formula's molar mass (88) to get 2. This means the molecular formula of Vitamin C is twice the empirical formula, so the molecular formula is C6H8O6.
Mass = Density x Volume
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.
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.
You can find the mass by dividing the momentum by the velocity. The formula for momentum is mass multiplied by velocity, so by rearranging the formula you can solve for mass by dividing momentum by velocity.
To determine the molecular formula, you would need the molar mass of the compound. With the molar mass, you can calculate the empirical formula mass and then determine the ratio between the empirical formula mass and the molar mass to find the molecular formula.
To determine the molecular formula from the empirical formula and gram formula mass, first calculate the empirical formula mass of C4H9 (4 carbons + 9 hydrogens). Then, divide the gram formula mass by the empirical formula mass to find the ratio. Finally, multiply the subscripts in the empirical formula by this ratio to get the molecular formula, which in this case is C8H18.
Find the mass of a known volume of the liquid and use the formula mass/volume to find the density.
