Question

36 grams of water vapor takes up how many liters at room temperature and pressure (293 K and 100 kPa?)

Answer 1

100kpa is correct If that is not wht you were asking i'd gladly fix it :)

Answer 2

Answer: The volume of water vapor is 48.7 L

Step-by-step explanation:

To calculate the number of moles, we use the equation given by ideal gas equation:

`PV=nRT`

Or,

`PV=(m)/(M)RT`

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 =
`8.31\text{L kPa }mol^(-1)K^(-1)`

T = temperature = 293 K

Putting values in above equation, we get:

`100kPa* V=(36g)/(18g/mol)* 8.31\text{L kPa }mol^(-1)K^(-1)* 293K\\\\V=48.7L`

Hence, the volume of water vapor is 48.7 L
