Mass = moles x molar mass
Molar mass of eythl alcohol = 46
Mass= 0.21 x 46= 9.66g
Your answer should be heat energy!
Answer: 0.024 M
Explanation:
According to the neutralization law,
where,
= molarity of stock solution = 0.12 M
= volume of stock solution = 20.0 ml
= molarity of diluted solution = ? M
= volume of diluted solution = 100.0 ml
Putting in the values we get:
Therefore, the concentration of the resulting solution is 0.024 M.
