Step 1
- Potassium (K) has a molar mass of approximately 39.10 g/mol. - Oxygen (O) has a molar mass of approximately 16.00 g/mol. - Hydrogen (H) has a molar mass of approximately 1.01 g/mol. - Therefore, the molar mass of KOH = 39.10 + 16.00 + 1.01 = 56.11 g/mol. Show more…

A student prepared a stock solution by dissolving 10.0 g of KOH in enough water to make 150. mL of solution. She then took 15.0 mL of the stock solution and diluted it with enough water to make water to make 65.0 mL of a final solution. What is the concentration of KOH for the final solution? a) 0.356 M b) 0.274 M c) 3.65 M d) 2.81 M
