How many moles of solute are present in 100 mL of 0.1 molar solution?

Answer and explanation

Correct answer: 0.01 mole

Molarity is moles of solute per litre of solution, so the volume must be expressed in litres. Convert 100 mL to 0.100 L, then use n = M × V = 0.1 mol L⁻¹ × 0.100 L = 0.010 mol. Hence, option A is correct. Options B, C, and D result from failing to convert millilitres or applying the formula incorrectly.
