What is the compound name of MgNO32?
The compound name for Mg(NO3)2 is magnesium nitrate.
What is the molecular formula of a compound with an empirical formula of C4H9 and a gram formula mass of 114 grams mole?
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.
What is relationship between the formula weight of a substance and its molar mass?
Formula weight is the sum of the atomic weights of all atoms in a chemical formula, while molar mass is the mass of one mole of a substance. They are related in that the formula weight and molar mass are numerically equal for elements and simple compounds. For more complex compounds, the molar mass is the sum of the atomic masses as obtained from the periodic table.
How does one determine a molecular formula from empirical 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.
What is the formula mass of hydrogen?
The relative formula mass of a molecule of hydrgoen is two (2 x 1).
What formula will be use to get average atomic mass on an isotopes?
mass formula
What is formula for mass?
There is no formula for mass. it is simply the weight measured in grams

Mass Times Volume is a formula for what?
Mass times volume isn't a formula for anything. You may be confused with mass divided by volume, which is the formula for density.
What is the formula of the formula mass?
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 of a molecule or an ion is?
The formula mass of a molecule or an ion is the sum of the atomic masses of all the atoms in the formula unit. This value is expressed in atomic mass units (amu) and is used to calculate the molar mass of the compound.

Formula for calculating mass?
The formula for calculating mass is mass = density x volume. This formula relates the mass of an object to its density (amount of matter in a given volume) and volume (amount of space an object occupies).
What is the formula mass of hydrogen?
The relative formula mass of a molecule of hydrgoen is two (2 x 1).
