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

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:

Or,

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 =

T = temperature = 293 K

Putting values in above equation, we get:

Hence, the volume of water vapor is 48.7 L
