2 mol of a solute is dissolved to make 4 litres of solution. What is the molarity?
Answer and explanation
Correct answer: A. 0.5 M
- Step 1: Molarity is moles per litre: M. Answer: 0.5 M. Why not the others: 8 M: multiplies the moles by the volume. 2 M: inverts the ratio. 500 M: converts litres to millilitres wrongly.
