M = n/V
M = 1.51
V = 0.730
1.51 = n/0.730
To solve this, multiply both sides by the V.
1.1023 = n
n = 1.1023 mol
Explanation:
Boiling point is the temperature at which vapor pressure of a liquid becomes equal to the atmospheric pressure.
More strong interactions present in the atoms of a compound more heat is required to break it. Hence, greater will be its boiling point.
As the boiling point of oxygen is 90 K so, at a temperature greater than it will change the state of oxygen from liquid to gas.
Similarly, the boiling point of nitrogen is 77 K so, at a temperature 95 K the state of liquid will also change from liquid to gas.
