Heat Capacity for Calorimeters.

[Daniel Yu 1E]

When you are doing thermodynamic calculations with solutions in calorimeters, why doesn't the mass/mol matter sometimes?
I've seen in some equations you need to use mass/ moles but in others it is ignored. Why is that?

[Kaylee Sepulveda 4G]

Heat capacity is a state function, but heat capacity is an intensive property. In contrast, specific heat capacity and molar heat capacity are extensive properties. Extensive means that it depends on the amount of material being affected, so mols or grams would be a factor in your calculations.

Here is a nice explanation of a bomb calorimeter calculation: https://www.youtube.com/watch?v=zEaMi5ob5Ig

What is the difference between a calorimeter and a bomb calorimeter?

What is the difference between a calorimeter and a bomb calorimeter?

I believe a calorimeter is just a thermally insulated container while a bomb calorimeter is a sealed container that is metal in water which is also in an insulated container.

[Aman Sankineni 2L]

The difference between the two is that a regular calorimeter is simply a "thermally insulated container" while in a bomb calorimeter, the reaction takes place in a sealed metal container that is immersed in water in an insulated container.
