100kpa is correct If that is not wht you were asking i'd gladly fix it :)
Answer: The volume of water vapor is 48.7 L
Explanation:
To calculate the number of moles, we use the equation given by ideal gas equation:
[tex]PV=nRT[/tex]
Or,
[tex]PV=\frac{m}{M}RT[/tex]
where,
P = pressure = 100 kPa
V = Volume = ?
m = mass of water vapor = 36 grams
M = molar mass of water = 18 g/mol
R = Gas constant = [tex]8.31\text{L kPa }mol^{-1}K^{-1}[/tex]
T = temperature = 293 K
Putting values in above equation, we get:
[tex]100kPa\times V=\frac{36g}{18g/mol}\times 8.31\text{L kPa }mol^{-1}K^{-1}\times 293K\\\\V=48.7L[/tex]
Hence, the volume of water vapor is 48.7 L
