Explanation:
Answer:
A 1.0 g sample of propane, C3H8, was burned in the calorimeter.
The temperature rose from 28.5 0C to 32.0 0C and the heat of combustion 10.5 kJ/g.
Calculate the heat capacity of the calorimeter apparatus in kJ/0C
Explanation:

Given,
The heat of combustion = 10.5kJ/g.

Substitute these values in the above formula to get the value of heat capacity of the calorimeter.

Answer:
The heat capacity of the calorimeter is 
Answer:
From Hawaii’s Maunakea, astronomers around the world use W. M. Keck Observatory to observe the universe with unprecedented power and precision.
The twin Keck Observatory telescopes are the world’s most scientifically productive optical and infrared telescopes. Each telescope weighs 300 tons and operates with nanometer precision. The telescopes’ primary mirrors are 10-meters in diameter and are each composed of 36 hexagonal segments that work in concert as a single piece of reflective glass.
In the middle of the Pacific Ocean, Hawaii Island is surrounded by thousands of miles of thermally stable seas. The 13,796-foot Maunakea summit has no nearby mountain ranges to roil the upper atmosphere. Few city lights pollute Hawaiian night skies, and for most of the year, the atmosphere above Maunakea is clear, calm and dry -— offering the best seeing on Earth.
