Question

36 g of water vapor takes up how many liters at room temperature and pressure of 293K and 100 K PA

Answer 1

Answer:-

48.72 L

Explanation:-

Chemical formula of water= H2O

Mass of water = 36 g

Molar mass of water = 1 x 2 + 16 x 1 = 18 g mol-1

Number of moles of water = n = 36 g / (18 g mol-1)

= 2 moles.

Temperature T = 293 K

Pressure = P = 100 K Pa

Universal gas constant R = 8.314 L KPa K -1 mol-1

Using the relation PV = nRT

we get Volume V = nRT/P

Plugging in the values

V = (2 moles ) x ( 8.314 L KPa K -1 mol-1) x ( 293 K) / 100 K Pa

= 48.72 L
