WebStep 1: First balance O atoms on both sides. For this multiply MgO with 2. In the above molecular equation, on the left hand side of the arrow contains one Mg atom and two O atoms where as right hand side of the arrow contains two Mg atoms and two O atoms. Step 2: Now balance Mg atoms on both sides. For this multiply Mg with 2. Weba. 2.0 moles of H X 3 P O X 4. b. 3.0 moles of H X 2 S O X 3. c. 4.0 moles of H N O X 3. d. 6.0 moles of H C l O. e. 8.0 moles of H B r. My logic would tell me that every mole has 6.022 × …
