I assume the question is to find the molecular mass of Ca(NO3)2 which equates to
Ca = 40
N = 14
O = 16
therefore
Ca(NO3)2 = 40 (14 + 48)2 = 164g
Molar (formula) mass of calcium nitrate is 164,1 9/mol
Molecular weight calculation: 40.078 + (14.0067 + 15.9994*3)*2
The molecular mass of anhydrous calcium nitrate is 164,088 g.
4,2 moles of anhydrous calcium nitrate is equal to 689,17 g.
Ca(NO3)2
relative formula mass of MgCO3
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.
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.
The relative formula mass of a molecule of hydrgoen is two (2 x 1).
CaNO3 does not exist. Ca(NO3)2 is calcium nitrate.
Molar mass of CaCO3 = 100.0869 g/molMolar mass of CaNO32 = 566.0655 g/mol
Three oxygen atoms in each nitrate ion multiplied by two nitrate ions results in 6 total oxygen atoms.
its Gram Formula Mass
The answer is 18,061.1023 atoms.
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
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.
A reaction doesn't occur.
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.
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).
