Explanation:
Let us assume that the given data is as follows.
V = 3.10 L, T = = (19 + 273)K = 292 K
P = 40 torr (1 atm = 760 torr)
So, P =
= 0.053 atm
n = ?
According to the ideal gas equation, PV = nRT.
Putting the given values into the above equation to calculate the value of n as follows.
PV = nRT
0.1643 =
n =
It is known that molar mass of ethanol is 46 g/mol. Hence, calculate its mass as follows.
No. of moles =
mass = g
= 0.315 g
Thus, we can conclude that the mass of liquid ethanol is 0.315 g.
