Question

5 ml of water at 4 degree Celsius (density 1 g/ml) is converted to steam at 110 degree Celsius. What volume will the steam occupy when pressure is 380 Torr?

Answer 1

The volume of the steam can be calculated using the Ideal Gas Law:

V = nRT/P

where n is the number of moles of water, R is the ideal gas constant (0.0821 L·atm/mol·K), T is the temperature in Kelvin (283.15 K), and P is the pressure in atmospheres (0.49 atm).

Therefore, the volume of the steam is:

V = (5 ml * 1 g/ml / 18 g/mol) * 0.0821 L·atm/mol·K * 283.15 K / 0.49 atm

V = 11.7 L
