Answer: The final molarity of a 20mL- 1.3M salt solution after it has been diluted with 100ml water is 0.22 M
Explanation:
According to the dilution law,
where,
= molarity of stock solution = 1.3 M
= volume of stock solution = 20 ml
= molarity of diluted solution = ?
= volume of diluted solution = (20+100) ml = 120 ml
Putting in the values we get:
Therefore the final molarity of a 20mL- 1.3M salt solution after it has been diluted with 100ml water is 0.22 M
