How many grams of sulfuric acid are in 350 grams of an 18% solution of this acid?
| May 21, 2021 | education
In order to determine the number of grams of sulfuric acid in the solution, it is necessary to multiply the total weight of the solution by the percentage of acid in it and divide by the total percentage, namely – 100%
In this case, we get.
350 * 18/100 = 63 grams.
Also, this problem can be solved by drawing up a proportion in which the total weight of the solution will refer to 100%, just like the unknown weight of the acid – x, to 18%.
We will receive.
350/100 = x / 18.
100 * x = 350 * 18.
100 * x = 6300.
x = 6300/100.
x = 63 grams.
