PLEASE I NEED AN ANSWER FOR THESE QUICK, 20 POINTS
An investigation has been completed similar to the one on latent heat of fusion, where steam is bubbled through a container of water. Steam condenses and the lost energy heats the water and container. Use the following data to answer the question below:

Mass of the aluminum container 50 g
Mass of the container and water 250 g
Mass of the water 200 g
Initial temperature of the container and water 20°C
Temperature of the steam 100°C
Final temperature of the container, water, and condensed steam 50°C
Mass of the container, water, and condensed steam 261 g
Mass of the steam 11 g
Specific heat of aluminum 0.22 cal/g°C

1. Given the data above, determine the total heat energy gained by the container and water.

2900 cal
6300 cal
6500 cal
7800 cal

2. Total heat lost by the steam as it condenses and reaches 50°C.

heat = 15,000 cal
6500 cal
5900 cal
3. Latent heat lost by the steam as it condenses to water at 100°C.

heat = 550 cal
6500 cal
5900 cal

4. What is the latent heat of vaporization for water?

latent heat = 540 kcal/kg
79.7 kcal/kg
5900 kcal/kg
5. Does the amount of heat energy lost by the steam equal that gained by the aluminum and water?

yes
no
