Ok. If you have 325 tubes of sunscreen then you have 325*4oz= 1300 oz of sunscreen and that must contain 0.025*1300 = 32.5 oz of BS. Now you wanted the answer in kg so...there are 28.375 g/oz and multiplying by 32.5 I get 922.188 g of BS...or 0.922188 kg of BS. But you'd probably be safe in saying 0.92 kg.

each tube has 0/1 oz (2.5% of 4)
325 tubes have 32.5 oz
32.5 oz is 0.921359502 kilograms
0.921359502 kilograms :)
