You can put this solution on YOUR website!
3% is same as 3/100. You can just cross multiply.
3%2F100+=+x%2F177
177%2A3+=+100x
531+=+100x
x+=+5.31g+of+Avobenzone
Then, do the same, but for 1,000 bottles, as the proportions remain the same.
3%2F100+=+x%2F1%2C000
100x+=+3%2C000
x+=+30g+of+Avobenzone
However, this asks for the answer in kilograms. Move the decimal point left four places.
It requires .03g of Avobenzone.
