Question

a sunscreen preparation contains 2.55 y mass benzyl salicylate. if a tube contains 5.0 oz of sunscreen, how many kilograms of benzyl salicylate are needed to manufacture 425 tubes of sunscreen?

Answer 1

To manufacture 425 tubes of sunscreen, approximately 30.6 kg of benzyl salicylate would be needed. This is calculated by converting the amount of benzyl salicylate from ounces to kilograms and then multiplying by the total number of tubes.

Step-by-step explanation:

This chemistry problem involves unit conversion and multiplication. Firstly, we need to convert the quantity of benzyl salicylate in each tube of sunscreen into kilograms, as we're given it in y (assumed to be ounces). The conversion from ounces to kilogram is approximately 0.0283495, hence 2.55 y (ounces) becomes about 0.072 kg.

Now, we need to calculate the amount needed for 425 tubes of sunscreen. The total amount of benzyl salicylate needed could be found by multiplying the amount needed for one tube (0.072 kg) by the total number of tubes (425). Therefore, the total amount of benzyl salicylate needed is around 30.6 kg.
