3 Calculate the energy needed to convert 0.75 mol of liquid water at 15°C to steam at 130°C. = 4.18 J/g°C, s = 1.84 J/g°C, A H (H,O) = 40.79 kJ/mol %3D vap water steam

2. Calculate the amount of energy (in kilojoules) needed to heat 346 g of liquid water from 0°C to 182°C. Assume that the specific heat of water is 4.184 J/gᵒC over the entire liquid range and that the specific heat of steam is 1.99 J/gᵒC. (AHvap = 40.79 kJ/mol for water)

A sample of steam with a mass of 0.521 g at a temperature of 100 oC condenses into an insulated container holding 4.50 g of water at 5.0 .C. For water, \Delta Hovap = 40.7 kJ/mol and Cwater = 4.18 J/(g-oC). Part A Assuming that no heat is lost to the surroundings, what is the final temperature of the mixture? Express your answer in degrees Celsius to three significant figures.

The vapor pressure of liquid SO, is 281.1 mmHg at a temperature of 242.0 K. The enthalpy of vaporization, AH, What is the vapor pressure of SO2 at a temperature of 250.0 K, in mmHg? for this liquid is 24.9 kJ/mol. чар"

Pentane C5H12 boils at 360C at 1 atmosphere pressure. What is the molar heat of vaporization in kJ/mol if the vapor pressure of pentane at 250C is 505 torr?
