HOW MANY GRAMS ARE IN 1.50 MOLES OF KMNO4
Web19 aug. 2016 · Explanation: Step 1. Calculate the molar mass of Fe2O3. molar mass = 2 × 55.84 g Fe + 3 × 16.00 g O = 111.68 g Fe + 48.00 g O = 159.68 g Fe2O3. This tells us that there are 111.68 g Fe in 159.68 g Fe2O3. Step 2. Calculate the mass of Fe. ∴ In 21.6 g Fe2O3, Mass of Fe = 21.6g Fe2O3 × 111.68 g Fe 159.68g Fe2O3 = 15.1 g Fe. Weba. 4.35 moles of KMnO_ {4} K M nO4 are dissolved in enough water to give 750 mL of solution. b. 20.0 g of NaOH is dissolved in enough water to give 1.50 L of solution.
