Q: How many moles are in 500 mL of a 2 M NaCl solution?
Solution:
Moles = molarity x volume (in L) = 2 M x 0.5 L = 1 mole.
Steps: 5
Show Steps
Step 1: Understand that 'M' in 2 M NaCl means molarity, which is moles of solute per liter of solution.
Step 2: Convert the volume from milliliters (mL) to liters (L). Since 1000 mL = 1 L, 500 mL = 0.5 L.
Step 3: Use the formula for moles: Moles = Molarity x Volume.
Step 4: Plug in the values: Moles = 2 M x 0.5 L.
Step 5: Calculate the result: 2 x 0.5 = 1 mole.
