The mass of a volatile liquid which fills a flask is 0.320 grams. If the density of the gas at STP is 3.0 x 10 g/mL, what is the volume of the glass? Show calculations. 1. 53 Would your experimental value for the molecular weight of your unknown be higher or lower than the true value if (also explain why): 2. The temperature of the boiling water which you measure is actually higher than the temperature of the vapor in the flask? You assumed they were the same. a. b. All the liquid in the flask is not vaporized?
Solution
Mass of the liquid = 0.320 grams. Density of gas = 0.003 grams/mL
The mass of the liquid and gas will be same.
We know,
density = mass / volume
0.003 gram/mL = 0.320 gram / V
V = 106.66 mL.
Therefore, volume = 106.6 mL.

1. The mass of a volatile liquid which fills a flask is 0.320 grams. If the density of the gas at STP is
3.0 x 10 g/mL, what is the volume of the glass? Show calculations. 1. 53 Would your
experimental value for the molecular weight of your unknown be higher or lower than the true
value if (also explain why): 2. The temperature of the boiling water which you measure is
actually higher than the temperature of the vapor in the flask? You assumed they were the same.
