## Answers

Answer: 0.4 * 10⁻⁶mol Explanation:The unit conversion required are , 1 μ M = 10⁻⁶ M1 L = 1000 mL1 mol = 1000 mmolmolarity of a solution is given as - Molarity (M) = ( w / m ) / V ( in L) where , m = molecular mass , w = given mass , V = volume of solution , Hence , the unit is , M = mol / Lfrom the question , 0.4 μ M = 0.4 * 10⁻⁶ MNow, 0.4 * 10⁻⁶ M = 0.4 * 10⁻⁶ mol / LSince , 1 L = 1000 mLand , 1 mol = 1000 mmol0.4 * 10⁻⁶ mol / L = 0.4 * 10⁻⁶ * 1000 mol / 1000 mL = 0.4 * 10⁻⁶mol
