Hey! got a butt load of hw due tomorrow pls brainliest answer included! solve. how much pure acid is in 520 milliliters of a 12% solution?

540ml  with 12% solution

get 12% of 540

540 times 0.12 = 64.8 ml of pure acid

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
