If you add 16g of salicyic acid to 84g of an ointment base what is the final concentration w/w of the product

w/W=16/100

To calculate the final concentration w/w (weight/weight) of the product, you need to determine the total weight of the product after adding the salicylic acid.

The total weight of the product is the sum of the weight of salicylic acid and the weight of the ointment base.

Given:
Weight of salicylic acid = 16g
Weight of ointment base = 84g

Total weight of the product = Weight of salicylic acid + Weight of ointment base
Total weight of the product = 16g + 84g = 100g

Now, to calculate the final concentration w/w of the salicylic acid, divide the weight of salicylic acid by the total weight of the product, and then multiply by 100 to get the percentage.

Final concentration w/w of salicylic acid = (Weight of salicylic acid / Total weight of the product) × 100
Final concentration w/w of salicylic acid = (16g / 100g) × 100
Final concentration w/w of salicylic acid = 16%

So, the final concentration w/w of the salicylic acid in the product is 16%.
