Answer:
The density of solution is 1.283 g/mL.
Explanation:
Molarity of the KOH before dilution =
Volume of the solution before dilution =
Molarity of the KOH after dilution =
Volume of the solution after dilution =
(1 mL = 0.001 L)
Mass of 0.2076 moles of KOH:
0.2076 mol × 56 g/mol = 11.6256 g
Mass of KOH is solution = 11.6265 g
Mass of the solution = M
Mass percentage of solution = 30.0% of KOH
M = 38.755 g
Density of the solution , d=
The density of solution is 1.283 g/mL.
