1. What will be the theoretcal yield of tungsten(s) ,W, if 45.0 g of WO 3 combines as completely as possible with 1.50 g of H 2 ? WO 3 (s) + 3H 2 (g) => W(s) + 3 H 2 O(g) 1. During a titration, the following data were collected. A 25 mL portion of an unknown solution was titrated with 1.0 M NaOH. It required 65 mL of the base to neutralize the sample. How many moles of
