1tsp * 5mL/tsp * 0.8g/1mL * 1mole/151g * 6.023*10^23molecules/mole
= 6.38 * 10^20 molecules
Vanillin is the key component of vanilla extract that gives it its unique flavor. Assuming that vanilla extract is composed entirely of vanillin molecules, if the density of vanilla extract is 0.8 grams per mL, how many molecules of vanillin are there in 1 tsp (5 mL)? The molecular weight of vanillin is 151 grams per mole.
