How to convert grams to moles with a formula Convert the density of 9.55 g/L to its equivalent in g/mL. How does one determine the formula of a salt? How to convert joules to BTU How do you convert grams into atomic mass unit?
amount of ½O2 is equal to 6 moles, n(½O2) = 6 mol.Thus n(½O2) = 2n(O2).(2) The definition applies to entities B which should always be indicated by a subscript or in parentheses, e.g. n B of n(B).(3) A formula unit is not a unit but an entity specified as...
Using grams in calculations instead of moles would be unwieldy and confusing.Grams and Moles A mole is a unit used to measure microscopic particles. As a unit of measurement, the mole is like a dozen or a gross. A dozen eggs means twelve eggs, whereas a gross of pencils means one ...
(molecule, formula unit) atomic mass constant mu mu = ma( 12 C)/12 kg (4) molar mass M MB = m/nB kg mol -1 (2), (5) (1) The words ‘of substance' may be replaced by the specification of the entity. Example When the amount of O2 is equal to 3 moles, n(O2) = 3 mol...

The formula unit is a term that generally refers to the formula of the compound (specifically to an ionic compound). The formula units will be calculated using Avogadro's number and the number of moles of the compound involved. Therefore, we must calculate the m...
Mole fraction may be a unit of concentration in chemistry. A mole is really a variety of molecules, approximately 6 × 1023. A mole fraction is the ratio of molecules of 1 component during a mixture. For instance, if the mole fraction of methane in gas is 0.90, then this suggests that...
