How much water should be added to 3 gallons of pure acid in order to obtain the 15% acid solution? HELP DUE BY TOMMOROW MORNING
1 answer:
3 gallons of acid = 100% concentration acid
? (water+acid) gallons = 15 concentration acid
Note: Every gallon of water added reduces the percentage concentration of acid. Therefore, the relationship is inverse proportionality.
Solution:
Total number of gallons (water+acid) = (3*100)/15 = 20 gallons
Therefore, gallons of water = 20-3 = 17 gallons

Answer:
1.5
Step-by-step explanation:
Let the number be denoted as "a"
-1 (2a + 3) = 2 (-4a + 3)
-2a - 3 = -8a + 6
-2a + 8a = 6 + 3
6a = 9
a = 9/6
a = 3/2 = 1.5
