Doreen Schmidt is a chemist. She needs to prepare 28 ounces of a 8% hydrochloric acid solution. Find the amount of 14% solution

scZoUnD [109]

Let, amount of 14% solution required is x ounces.

So, amount of 8% solution will be ( 28 - x ) ounces.

Now, mathematical equation is :

$\dfrac{14x}{100}+\dfrac{7(28-x)}{100}= \dfrac{8\times 28}{100}\\\\14x + 196 - 7x = 224\\\\7x = 28\\\\x = 4\ ounces$

Therefore, amount of 14% solution and 8% solution required is 4 ounces and 24 ounces respectively.

Hence, this is the required solution.

which is a good comparison of the estimated sum and the actual sum of 7 10/12+2 11/12? Greater or lesser

Crazy boy [7]

I would estimate 7 10/12 to 8 and i would estimate 2 11/12 to 3 so 8 plus 3 would equal 11 so that would be the estimate. the actual would be 10 8/11 so the estimate would be bigger.
