Achemist is using 371 milliliters of a solution of acid and water. if 17.7% of the solution is acid, how many milliliters of acid are there? round your answer to
the nearest tenth.

There are 65,7 ml of acid.

Step-by-step explanation:

This is a percent problem. When we have a total (in this case 371 ml of a solution), it's value is the 100%. As only 17,7% is only the part we are interested in (acid), we shall get a cross-multiplication like this one:

371 ml ----------- 100%

x=       ------------17.7%

This must be resolved multiplying 17.7 x 371 and dividing the result by 100.

This number rounded to the nearest tenth is 65,7.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
