To do this, you need to find a way to relate the mass of a compound (salt) to the number of moles of that compound. The molar mass of elements tells you the molar mass of a compound, so you can figure this out.

39 g and 0.32 g , respectively, and they are mixed together. Tollens' reagent is added to the system and it has been calculated that for complete oxidization of both aldehydes 0,0202 moles of Ag+ ions have been used. Calculate the molar mass of A and B. The problem is that the...
The molar mass of a chemical substance commonly indicates the total available mass of a chemical substance in its unit mole. Generally, the product of the total number of moles and the molar mass of a chemical substance is used to determine the mass of a chemical substance. ...
Calculate the molar mass of {eq}PbSO_4 {/eq}.Molar Mass:We can determine the molar mass of any given compound if the chemical formula is provided (contains the elements and the ratio with one another). The subscript in the chemical formula of the compound will be a factor in the ...
1st Step: Calculate the empirical formula from percentage composition. 2nd Step: Calculate the Empirical Formula mass (EFM) by adding up the molar atomic masses of all atoms constituting the formula. 3rd Step: Determination of the Molar Mass of the given compound. 4th Step: Determination of the...
