Question

I need help on this question 

Calculating the molar mass of a substance involves three simple steps: 1. Obtain the molar mass of each element. 2. Multiply each element's molar mass by the number of moles of that element that are present in one mole of the compound. The subscript immediately following an atomic symbol in a molecular formula indicates how many moles of that element are present in one mole of the compound. 3. Calculate the molar mass by adding the masses of the elements. Compound Calculation Molar mass BeF2 (9.012 g/mol)(1 mol) + (19.00 g/mol)(2 mol) 47.01 g/mol MGF2 (24.31 g/mol)(1 mol) + (19.00 g/mol)(2 mol) 62.31 g/mol COF2 (58.93 g/mol)(1 mol) + (19.00 g/mol)(2 mol) 96.93 g/mol PDF2 (106.42 g/mol)(1 mol) + (19.00 g/mol)(2 mol) 144.42 g/mol
