A sunscreen preparation contains 2.50% benzyl salicylate by mass. If a tube contains 4.0 oz of sunscreen, how many kilograms of benzyl salicylate are needed to manufacture 325 tubes
of sunscreen?

We must solve this through a multi-step dimensional analysis process, but I am having trouble since there is a percentage present in the question. Any help would be appreciated!
