Answer:
34%
Step-by-step explanation:
To find the concentration of the new solution, take the percent time the amount of each of the solutions
40 ml* 25% + 60 ml * 40% = 100 ml* percent
40 * .25 + 60 *.40 = 100 * P
10 + 24 = 100 P
34 = 100 P
Divide each side by 100
34/100 = P
.34 = P
Changing to
34%
Answer:
b = Q/f
