b) the time taken to reach this height. (neglect the effect of air resistance).
a. the mass of air in the flask before connecting to vacuum pump, in g
b. the density of the air in the flask
(a) The mass of air in the flask before connecting to vacuum pump is 30.98 g
(b) The density of the air in the flask is 0.155 g/cm³
The given parameter:
volume of the flask, V = 200 cm³
the initial mass of the flask, m = 30.98 g
final mass of the flask = 30.72 g
To find:
The mass of air in the flask before connecting to vacuum pump is 30.98 g
The density of the air in the flask is calculated as:
