Calculate the molar mass of each of the following: (6.5)a.

Solution 104 AQPHere, we are calculating the molar mass each of the following.To calculate the molar mass of each element by its subscript in the formula.Step 1 of 3a.Mg(HCO3)2First, let’s write the molar mass of each element in the Mg(HCO3)2Molar mass of Magnesium = Molar mass of Hydrogen = Molar mass of Carbon = Molar mass of Oxygen = Let’s multiply each molar mass by the number of moles (subscript) in the formula.Grams from 1 mole of Magnesium 1 mole Magnesium = 24.3 g of Mg.Grams from 2 mole of Hydrogen 2 mole of Hydrogen = 2.0 g of HGrams from 2 moles of Carbon 2 moles of Carbon = 24.0 g of CGrams from 6 moles of Oxygen 6 mole of Oxygen = 96.0 g of O.Let’s calculate the molar mass of Mg(HCO3)2by adding molar masses of elements 1 mole of Mg = 24.3 g 2 moles of H = 2.0g 2 moles of C = 24.0g 6 moles of O = 96.0 g________________________________________ Molar mass of Mg(HCO3)2 = 146.3 gTherefore, Molar mass of Mg(HCO3)2 is 146.3 g______________________________________________________________________________
