You can work out the molecular formula from the empirical formula, if you know the relative mass formula (M r) of the compound. Add up the atomic masses of the atoms in the empirical formula.

1. Convert kilograms/second to grams per second. 1 kg = 1000 grams. If the mass flowrate is 0.25 kilograms/second, convert this to 250 grams/second. 2. Convert grams to moles, using the molar mass of ...

What are the units of molarity? The units of molarity are M or mol/L. A 1 M solution is said to be “one molar”. Two solutions that have the same molarity will have the same number of molecules of the ...
