Answer to Question #77378 in General Chemistry for Kristina

Question

An aqueous solution has a hydroxide ion concentration of 4.49 x 10-11 M. Calculate the number of moles of hydroxide ions in 8.14 L of solution.

Answer 1

Answer:
Number of moles of hydroxide ions will be calculated using the following equation
Moles = Volume x Concentration (n = V x c) = 8.14 L x 4.49 x 10^(-11) moles/L = 36.55 x 10^(-11) moles
