Gallium oxide decomposed to produce 0.12 grams of Given: reactants, products, and mass of one reactant. This is to cancel out BaCl2 and leave AgCl. So, butter is an oily . Finally, convert the mass of H2 to the desired units (tons) by using the appropriate conversion factors: \[ tons \, H_2 = 1.14 \times 10^5 \, g \, H_2 \times {1 \, lb \over 453.6 \, g} \times {1 \, tn \over 2000 \, lb} = 0.126 \, tn \, H_2 \nonumber \]. In most cases, this is the unit we use to measure the total mass of the sample. Even though 2 mol of H2 are needed to react with each mole of O2, the molar mass of H2 is so much smaller than that of O2 that only a relatively small mass of H2 is needed compared to the mass of O2. It immediately converts to the normal form. B To convert tons of oxygen to units of mass in grams, we multiply by the appropriate conversion factors: \[ mass \, of \, O_2 = 1.00 \, tn \times { 2000 \, lb \over tn} \times {453.6 \, g \over lb} = 9.07 \times 10^5 \, g \, O_2 \nonumber \].
