Determine the molar mass
WebTo calculate the percent composition, the masses of C, H, and O in a known mass of C 9 H 8 O 4 are needed. It is convenient to consider 1 mol of C 9 H 8 O 4 and use its molar mass (180.159 g/mole, determined from the chemical formula) to calculate the percentages of each of its elements: % C = 9 mol C × molar mass C molar mass C 9 H 8 O 4 × ... WebMolar mass is an important concept in chemistry because it allows for the conversion of mass to moles and vice versa. This is particularly useful when conducting chemical reactions. For example, if we know that we need 2 moles of a substance to react with another substance, we can use its molar mass to determine how much mass of that …
