c × M. 10. To get v/v percentage, multiply molarity by molar mass of the substance and divide by 10 times the mass density of the solution. Cv/v. =. c × M. 10 × ρ. You can use the third calculator (from page top) to calculate a dilution or preparation of a stock solution. For that, the following formulas will be used:
How to Calculate Mass Percent 13 Steps (with Pictures) wikiHow
Using our Molecular Weight Calculator we can easily get 30.026 g/mol. Next, we divide the molecular weight of the substance under study by the just found molecular weight of the empirical formula and obtain: 180.16 / 30.026 = 5.954. After rounding this result to a whole number we have n = 6, and obtain the molecular formula of glucose: C 6 H 12.

The molecular weight or molecular mass (the terms are, quite incorrectly, used equivalently) is the mass of a molecule.. The molecular weight is a fundamental property of any substance, highly affecting many chemical and physical properties like viscosity, diffusion, and melting temperature.. In molecules like polymers, the molecular weight determines the nature of the final material.
Question Video Calculating the Mass of a Reactant in a Reaction with Stoichiometry
Molecular weight (or molecular mass) is the mass of a molecule given in the dalton unit ( Da) or the unified atomic mass unit ( u ). This one roughly corresponds to the mass of a single proton or neutron. For example, the molecular weight of CO 2 is 44.01 Da or 44.01 u.

Find your elements in the periodic table of the elements. The atomic mass is usually shown below the symbol of the element. C - 12 u; H - 1 u; and. O - 16 u. Input the values into the molecular weight equation and calculate the result: MW = (6 * 12u) + (12 * 1u) + (6 * 16u), MW = 180 u. We got the right answer - the molecular weight of glucose.
