Sagot :
Answer:
70 %
Explanation:
Use the formula x = (c ÷ V) × 100 to convert the concentration (c) and volume (V) of the final solution to a percentage.
given: c = 350 ml and V = 500 ml.
Solve for x, which is the percentage concentration of the final solution.
x = (350 ml ÷ 500 ml) × 100
x = 70 percent (answer)
Therefore , the final concentration of the solution is 70 % .
good luck!
