Mass

If you know an object's weight, you can calculate its mass from the formula m = F/a where m is mass in kilograms and F is Force in newtons, and a is the acceleration (one can use the acceleration of Earth's gravity, which is 9.81 m/s2 ). The Kilogram is SI unit for mass. It is a unit that can be converted to a weight (any mass applied against a surface that is experiencing acceleration in the direction opposite the application of the mass object to the said surface), in USA. pounds (lbs) i.e. 1 lb = 2.2 kg, where it is understood that the kg in question is being accelerated. The Mass of an object, as such, can be measured equally in gravity here on earth, and in space where there is little gravity, by a horizontal spring balance, while the weight of said object varies depending upon which planet you are standing, using a vertical spring balance. The 'weight' of an object generates a Force against a surface, in an acceleration field, such as gravity. The kilogram is the measure of matter's mass. The mass standard is a simple cylinder of a specific volume, made of an alloy of platinum and iridium.

If you know how many protons and neutrons there is in the atom you add them up and youll get the atoms mass.

# of protons + # of neutrons = Atomic Mass

(the # of protons is the atomic number located on top of the element symbol on the Periodic Table)

The Mass Number of an element is computed as the sum of proton and neutron.

Mass Number = no of protons + no of neutrons

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.

Oxidation number

The formula mass of a compound that contains the element would be a larger number than the mass number of the individual element. The individual element would simply be the mass of just that one atom, where as the compound would be the mass of that atom plus the other masses of the other atoms that make up the compound. ex. Oxygen-O has a mass number of about 16 grams. Water-H2O has a formula mass of 2 x mass of Hydrogen-H (about 1) + the mass of Oxygen-O 16 = 18 grams. A formula mass of 18 g is more than a mass number of 16 g.

Atomic mass is equal to the number of protons + neutrons present in the nuclide. The atomic number is defined as the number of protons in the nuclide. Therefore to find the number of neutrons use the formula: atomic mass = #protons + # neutrons solving for # of neutrons you get: # neutrons = atomic mass - # protons plug in the given values: #neutrons = 31 - 15 # neutrons = 16

The molecular mass number of methylene chloride is 50.5 g/mol.
