CHEMISTRY WORKSHEET # 2 MOLE PROBLEMS—THE MOLE …

Now that you know how to find the mass of one mole of a substance (molar mass) you can easily find the mass of several moles or the mass of a fraction of a mole using the factor-label technique. EXAMPLE: What is the mass of 5.00 moles of water(H20)? 2 H = 2 x( 1.01) = 2.02 # grams H20 = 5.00 moles H20 x 18.02 g H20 = 90.10 g H2O ................
