Formula mass calculation:
(2 x Molar mass of Carbon) + (2 x Molar mass of Hydrogen) = ___ amu
molar masses can be obtained from Periodic Table

What is the formula mass of calcium fluoride CaF2?
73.5 or 78.08 amu
What is the formula mass for ammonium sulfate NH42SO4 which is used in the biochemical treatment of wastewater?
132.15 amu
The molecular formula mass of this compound is 210 amu What are the subscripts in the actual molecular formula Enter the subscripts for C H and O?
Element Element's atomic massC : 12H2 : 2(hydrogen's atomic mass is 1 but remember there are two)O : 16Add all the elements atomic mass and then divide the molecular mass by it. After that you only need to multiply all the subscripts of each element to find your answer.12+2+16=30240/30=88(CH2O) = C8H16O8
In the compound Cu2OH2CO3 which element is present with the largest percent by mass?
From the formula of the compound, each molecular unit contains 2 copper atoms, 4 oxygen atoms, one carbon atom, and 2 hydrogen atoms. Multiplying each of these by its corresponding atomic mass gives 127 atomic mass units ("amu") of copper, 64 amu of oxygen, 12 amu of carbon, and 2 amu of hydrogen. Copper is clearly present in the largest percent by mass.
How do you convert 50 g of calcium carbonate into moles?
1. Calculate formula massCalcium carbonate has chemical formula CaCO3.Its formula mass is 40.1 + 12.0 + 3(16.0) = 100.12. Apply formula to calculate number of moles of CaCO3Amount of CaCO3= mass/formula mass= 50/100.1= 0.50mol

How do you calculate relative formula mass?
An example of how to get formula mass is shown below with the example of water (H2O). H2O 2 H atoms x 1.01 amu/atom = 2.02 amu 1 O atom x 16.00 amu/atom = 16.00 amu 2.02 amu + 16.00 amu = 18.02 amu
