Webstep 2-Using the periodic table, find the molar mass for each element, then multiply the value by the number of moles in the empirical formula. Carbon: 12 g/mol × 2 mol = 24 gHydrogen: 1 g/mol × 6 mol = 6 gOxygen: 16 g/mol × 1 mol = 16 g. step 3-Total the molar mass of each element to get the molar mass of ethanol. 24 g + 6 g + 16 g = 46 g. WebEmpirical Rule Formula Empirical formula states that \[mode=3median-2mean\]. This means we have to calculate mean and median of the given data and then use the formula to find mode. For finding the mean, we will add all the terms and then divide by total number of terms.6 days ago
