What is the number of moles in 500 mL of a 2 M NaCl solution? (2023)
Steps
Concepts
Step 1: Understand that Molarity (M) is the number of moles of solute per liter of solution.
Step 2: Identify the given values: Molarity (2 M) and Volume (500 mL).
Step 3: Convert the volume from milliliters to liters. Since 1000 mL = 1 L, 500 mL = 0.5 L.
Step 4: Use the formula for moles: Moles = Molarity x Volume (in liters).
Step 5: Plug in the values: Moles = 2 moles/L x 0.5 L.
Step 6: Calculate the result: 2 x 0.5 = 1 mole.
