Find the moles of Mg. Show work for at least one trial 2. Determine the pressure of Hagas. Use your data and Table 6.1 and rearrange Pusheepdogan Pow to find Phyerges (How many torr 1 atm?) Show work for at least one trial. Prydrogen 3. Convert the ambient temperature from "C to Kelvin. Cirde your answer.

Answer 1

1. Moles of H2 in trial 1 = PV/RT = 765.8 torr * (14/1000) L/{62.364 L L.torr/mol.K* (25.5+273) K} = 5.759*10^-4 mol

2. Table 6.1 is not given!

3. Ambient temperature = 25.5 + 273 = 298.5 K
