Calculate and compare the value for the molar volume at 21.5 °C obtained in part 2 with the value for the molar volume at 21.5 °C obtained in part 1. The molar mass of Zn is 65.38 g/mol?
How did using twice the amount of Zn in the second part of the experiment impact the molar volume? Explain your answer.
From the data recorded in the table below, calculate the pressure that would be observed.
temperature21.5 ºC
moles H2 5.25 x 10^-3mol
