A 0.0600-L sample of a 2.50M solution of potassium iodide contains what mass of KI?

Answer 1

To calculate the mass of KI in the solution, we can use the formula:

Mass = Volume x Concentration x Molar Mass

First, let's calculate the number of moles of KI in the solution:

Volume = 0.0600 L
Concentration = 2.50 M

Moles = Volume x Concentration
Moles = 0.0600 L x 2.50 mol/L
Moles = 0.15 mol

Next, we need to calculate the molar mass of KI:

Molar Mass of KI = 39.10 g/mol (K) + 126.90 g/mol (I)
Molar Mass of KI = 166.00 g/mol

Now, we can calculate the mass of KI in the solution:

Mass = Moles x Molar Mass
Mass = 0.15 mol x 166.00 g/mol
Mass = 24.90 g

Therefore, the mass of KI in the 0.0600-L sample of a 2.50M solution of potassium iodide is 24.90 grams.
