If a tube contains 2.0oz of sunscreen, how many kilograms of benzyl salicylate are needed to manufacture 325 tubes of sunscreen

Now it is given here that there are 325 tubes that are manufactured for sunscreen. And we also know that the percentage of sunscreen in benzyl salicylate is 2.5% here in one tube we have 2 Oz of sunscreen.

Explanation:

So sunscreen in 325 tubes will be 2 x 325 = 650 Oz. Since we know the amount of sunscreen in 325 tubes the amount of Benzyl salicylate in all 325 tubes will be 650 x 0.025 = 16.25 Oz

Now this can be converted into kg as 0.46 kg.
