From the experiment, it was found that the external pressure was 1.05 atm at 30.0 °C, and the volume of the air inside the eudiometer was 33.5 mL. The water level inside the eudiometer is 4.15 cm below the surface of the water level outside. ● At 30.0 °C, Pvapor = 31.8 mmHg ● R = 0.08206 L-atm/mol-K = 62.36 L-torr/mol-K ● MWAl = 26.98 g/mol Find the value of the pressure of dry air (PDA) in torr and give the balanced chemical reaction of the aluminum metal with the acid.
In an ideal gas experiment performed with some modifications, the students used
0.029 g of aluminum foil instead of magnesium ribbon. They prepared the eudiometer by adding 6M HCl and
filling it with water to the brim. Once the setup was complete, they performed the
experiment. Note that the aluminum was completely consumed in the reaction.
From the experiment, it was found that the external pressure was 1.05 atm at
30.0 °C, and the volume of the air inside the eudiometer was 33.5 mL. The water
level inside the eudiometer is 4.15 cm below the surface of the water level
outside.
● At 30.0 °C, Pvapor = 31.8 mmHg
● R = 0.08206 L-atm/mol-K = 62.36 L-torr/mol-K
