Given:
Total solution : 1000mL
Pure acetic acid = 26mL
To find:
The percent concentration of given solution.
Solution:
We know that,

Putting the given values, we get



Therefore, the percent concentration of this solution is 2.6%.
Answer:
136000×2000\8×100 do like that the answer is come
-6/8
The slope formula is m=(y2-y1)/(x2-x1)
Since 4 pastries is $10. Divide 10 by 4 to find out how much it cost per pastry.
10/4 = $2.5 per pastry
$2.5 * 9 pastries = cost
For 9 pastries, it cost $22.50
Plug it into the table :)
The domain is {-9,-4,3,9}
The range is {2}
