Question

How many moles of KI are contained in 258.6 mL of 0.0296 M KI solution?

Answer 1

0.0077 moles KI

Step-by-step explanation:

From the definition of Molarity (M) solve for moles, substitute and determine #moles. That is, Molarity (M) = moles solute/Liter solution => moles solute = Molarity(M) x Volume(L) = 0.0296M x 0.2586L = 0.0077 moles KI.
