Final answer:
An everyday situation analogous to finding the molecular formula from the empirical formula and molar mass is baking a cake using a recipe.
Step-by-step explanation:
An everyday situation that is analogous to finding the molecular formula when you know the empirical formula and the molar mass is baking a cake using a recipe. With a recipe, you may know the proportions of ingredients (empirical formula) and the total amount of ingredients needed (molar mass), but you need to determine the specific quantities of each ingredient (molecular formula) to get the desired outcome.
