Here is the following question:

How much heat, in kilojoules (kJ), is required to raise the temperature of 2.50 kg of Hg (l) from -20ºC to -6ºC? Assume a density of 13.6 g/mL and a molar heat capacity of 28.0 J mol^-1 ºC^-1 for Hg(l).

How can I make the molar heat capacity to specific heat capacity? So I can use q = m x C x deltaT

[Borek]

What is a molar mass? What is a specific heat capacity?

[TheGreatDeath]

molar mass of Hg is 200g/mol

specific heat capacity is in J/gºC


so is it like this?


  28 J       mol
---------  x -------  = 0.14 J/gºC   
mol ºC     200g

[Borek]

Yep.
