![]() ![]() ![]() The molecular weight can be obtained from the molecular formula, data tables, or the label on the bottle containing the chemical of interest. 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). Molecular mass (u) of Sulphuric acid (H2SO4) 2 x mass of H atom + mass of S atom + 4 x mass of O atom 2×1+32+4×16 98. 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).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. A 1 M solution is one in which exactly 1 mole of solute is dissolved in a total solution volume of exactly 1 L. If the substance is an element then the output of this calculator will also contain the number of atoms of that element. Molarity is defined as the number of moles of solute dissolved per liter of solution (mol/L = M). This mole conversion calculator also helps you calculate molar mass of a substance using a similar mathematical approach but in less time. This is also referred to as molarity, which is the most common method of expressing the concentration of a solute in a solution. C is the molar concentration in mol/L (Molar or M).
