Determine the molecular formula for the unknown if the molecular mass is 60.0 amu and the empirical formula is CH2O.?
C2H4O2=molecular formula, basically you multiply the empirical formula by 2.
If an unknow gas diffuses 0.25 times as fast as Helium. What is the molecular mass of the unknown gas?
64g/mol
What is the procedure to calculate the density of an unknown substance?
divide mass and volume(:
An unknown sample with a molecular mass of 180.0g is analyzed to yield 40 percent C 6.7 percent H and 53.3 percent O What is the empirical formula and the molecular formula of this compound?
ch2o and c6h12o6
What is HRMS weight?
High resolution mass spectrometry weight. It is used to narrow down the molecular formula of an unknown molecule.

Is the volume of the unknown mass needed to calculate the mass of calcium oxide?
No. you will know the volume of the unknown mass after you calculate the mass of ca0
What are some scary things that begin with the letter U?
People are afraid of uncertainty, undertow, unemployment, unknown and ulcer.
How does one determine a molecular formula from the empirical form?
molar mass of unknown/molar mass of empirial = # of empirical units in the molecular formula. Example: empirical formula is CH2O with a molar mass of 30. If the molar mass of the unknown is 180, then 180/30 = 6 and molecular formula will be C6H12O6
