Heat capacity of a polystyrene sulfonate ion-exchanger has been investigated with a TIAN-CALVET microcalorimeter as a function of the water content. Three ionic forms K +, Na + and Ba 2+ were examined. The partial molar heat capacity of water has been then deduced. The observed variations ...
This means that in the units you should include mol instead of grams. Instead of grams, you need to convert into mol. This requires use of the molar heat capacity formula. That means you need the specific heat of water and the molar mass of water. The molar mass of water is 18.0 g/...

What is the heat capacity of 1.49 moles of liquid water? If the specific heat capacity of water in the liquid state is 1.0cal/g degrees Celcius, calculate the molar heat capacity of water in J/mol degrees Celcius. The specific heat of water is 4.18 \dfrac{J...
The molar heat capacity of water at constant pressure is 75 JK−1mol−1. When 1.0 kJ of heat is supplied to 100 g of water which is free to expand the increase in temperature of water is A2.4 K B3.6 K C4. 8 K D1.2 KSubmit The molar heat capacity of water at constant pressur...
The data suggest that the molar heat capacity of an aqueous dispersion depends on the solvent-accessible surface area of starch grains, which determines the solubility and water-retaining capacity of these systems.关键词: anchored substrate cyclodextrin subtilisin catalysis ...
Being able to find the the molar heat of a combustion candle is a necessary skill for passing basic chemistry. It centers around an experiment where a teacher has the student light a candle underneath a pail of water for a set period of time. Using the c
