QUESTION:
If 10.00 g of water are introduced into an evacuated flask of volume 2.500 L at 65C, calculate the mass of water vaporized. (Hint: Assume that the volume of the remaining liquid water is negligible; the vapor pressure of water at 65C is 187.5 mmHg.)
ANSWER:Step 1 of 3
According to ideal gas law, the number of moles can be calculated by the following formula.
........................(1)
Rearrange the formula(1)
.......................(2)
Here,
P = pressure
V = Volume
n = Number of moles
R = Gas constant
T = Temperature.
