Web3 aug. 2014 · $\begingroup$ It's impossible to find the mass of water. The problem is asking for the molar mass of the compound. Assume 1 mol of compound, use the definitions of molarity and molality, find the weight of the compound and as you assumed 1 mol of it, the number you found is going to be the molecular mass. $\endgroup$ – WebThe formula for molarity is simply a conversion of the above expressions. Mass / volume = molarity * molar mass, after that mass / (volume * molar mass) = molarity. Substitute all known values for the calculation of molarity: molarity = 5 / (1.2 * …
