Answer:
0.66 gal.
Step-by-step explanation:
The following should apply:
C1 * V1 = C2 * V2
we have that C1 is 0.1, that C2 is 0.3 and that V1 is equal to 2 gal
replacing the values we have that:
0.1 * 2 = 0.3 * V2
reorganizing the equation we have:
V2 = 0.1 * 2 / 0.3 solving this remains 0.66.
It means that the amount of solution 2 is 0.66 gal.
