Ca = 40 x 3 = 120 grams
P = 31 x 2 = 62 grams
O = 16 x 8 = 128 grams
Add them together and you have 310 grams. This is the mass in grams of your formula. It is expressed in grams/mole because 310 is the weight of one mole of
Ca3(PO4)2.

What is the Grand formula mass?
its Gram Formula Mass
A compound with the empirical formula SN was found in a subsequent experiment to have a molar mass of 184.32 gmol. What is the molecular formula of the compound?
The empirical formula of SN has a formula unit mass of the sum of the gram atomic masses of nitrogen and sulfur, i.e., about 46.0667. The gram molecular mass given in the problem divided by this formula unit mass is about 4. Therefore, the molecular formula is S4N4.
What is the formula mass of nitrogen hydride?
Nitrogen hydride has the chemical formula of NH3 The gram formula mass of nitrogen is approximately 14.0 g/mole & the gram formula mass of hydrogen is approximately 1.0 g/mole In the chemical formula, you have 1 nitrogen atom and 3 hydrogen atoms 14.0 + 1.0 + 1.0 + 1.0 = 17.0 g/mole
The gram-formula mass of no2 is defined as the mass of?

What mass of sodium chloride contains 4.59 exp24 formula units?
The gram formula unit mass of sodium chloride is 58.443, and every gram formula unit mass contains Avogadro's Number, 6.022 X 1023 formula units. Therefore, the mass sought is 58.443 X (4.59 X 1024)/(6.022 X 1023) or 445 grams, to the justified number of significant digits.

How the moleculer formula of a compound is calculated if its emperical formula is known?
The gram molecular mass of the molecule must be measured by some independent method such as freezing point depression or boiling point elevation. Then the factor by which to multiply all of the subscripts in the empirical formula to get the molecular formula is the closest integer to the ratio of gram molecular mass to the gram molecular mass of a single unit of the empirical formula.
Why can't a substance have an empirical formula of NO and a gram formula mass of 45g?
From the Periodic Table The Atomic mass of Nitrogen (N) is 14 The Atomic mass of Oxygen (O) is 16 Hence the gram formula mass of NO is 14 + 16 = 30 Now NO under certain circumstances can form N2O2 hence the gram formula mass of N2O2 = (2 x 14) + ( 2 x 16) = 28 + 32 = 60 However the empirical formula is the formula with the lowest ratio of atoms. Hence N2O2 lowest ration is NO # formula mass is 30 .
