![]() so one can place 12.1 mL of the stock solution in 1000 mL volumetric flask & dilute. Identification of SULFURIC ACID Chemical Compound 98.07848 g/mol sulfuric acid OS(O)(O)O InChI1S/H2O4S/c1-5(2,3)4/h(H2,1,2,3,4) QAOWNCQODCNURD. thus molarity of stock solution is 16.53 M. From the calculation, you need to pipette 4 mL of the 5 M sulfuric acid. The molecular weight can be obtained from the molecular formula, data tables, or the label on the bottle containing the chemical of interest. number of mole of H2SO4actual mass/ molar mass 1620÷ 9816.53. The molarity of the F solution can be calculated from the mass, molar mass. ![]() Molecular weight is also referred to as formula weight and, in fact, many scientists prefer to use the latter. Note that V is the final or total volume of solution after the solute has been added to the solvent. V is volume of solution in liters (L) in which the indicated mass ( m) of solute must be dissolved to make the desired molar concentration ( C).m is the mass (i.e., weight) of solute in grams (g) that must be dissolved in volume V of solution to make the desired molar concentration ( C).He said that it would most likely go to two significant figures. Using SI prefixes, the concentration may also be expressed in different fractions of the molar concentration such as mmol/L (mM), μmol/L (μM), nmol/L (nM), pmol/L (pM), etc. In my chemistry discussion this morning, my TA informed our class that we will be given a periodic table to use during the test. ![]() A 1 M solution is one in which exactly 1 mole of solute is dissolved in a total solution volume of exactly 1 L. Answer (1 of 15): Molar mass is defined as the mass of a given substance(here, H2SO4) divided by the amount of that substance(in mol). Molarity is defined as the number of moles of solute dissolved per liter of solution (mol/L = M). This is also referred to as molarity, which is the most common method of expressing the concentration of a solute in a solution.
