Calculate the molar mass of a substance given its chemical formula. The calculator also provides information on the individual elements in the formula.
Moreover, molarity is expressed as the quotient of the number of the moles of the substance and the volume of the solution in liters.Answer and Explanation: We want to determine the mass of the substance, m, that is needed in orde...
The molecular mass is: 0.2720 g/4.500 × 10–3mol =60.44 g/mol You get 1 point for the correct number of moles of HA (or NaOH) and 1 point for the correct final answer. c.The approximate formula mass from the empirical (CH2O) formula is: 12 + 2(1) + 16 =30 g/mol ...
