What is the molar mass of benzene? - Socratic
网页2017年8月10日 · To find the molar mass of a compound, we first look at a periodic table to find the molar masses of each element in the compound: The chemical formula for benzene is. C6H6 −−−− −. So we need only look at the values for carbon and hydrogen. We find that the molar masses are. C: 12.01 g/mol.
Benzene and acetylene have the same empirical formula, CH
网页2018年6月28日 · molecular formula for benzene = C_6H_6 acetylene = C_2H_2 Since the question already gave the empirical formula for both compounds, which is CH. Let's figure out the subscript, n, in (CH)_n for their molecular formulas. To do so, let's use the molar mass and divide by the formula mass of the empirical formula, CH, 12 + 1 = 13 g. For …
