Please help. Heating 1.29 g of gallium gives a gallium-oxygen compound with a mass of 1.73 g. Calculate the empirical formula of the compound by following the next four steps. Step 1: Figure out how many grams of oxygen are in the 1.73 grams of gallium-oxygen compound. The grams of oxygen is A) 1.73 g + 1.29 g = 3.01 g B) 1.73 g / 15.99 g = 0.108 C) 1.73 g – 1.29 g = 0.44 g Step 2:...
