In the recipe for mayonnaise, the phospholipids in the egg yolk act as emulsifiers. If you assume that one egg yolk weighs 10g, that about 33% of this is fat, and that the majority of the fat is phospholipids. If you take the average molecular weight of a phospholipid to be 800 g/mol. How many phospholipid molecules are there in one egg yolk? Give your answer in molecules, but without entering the unit. Enter the number in scientific notation with the form #.#e##

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
