Question

The molar specific heat capacity of chromium at room temperature is 24 j/k mol and its atomic mass is 52g what is specific heat capacity of chromium?

Answer 1

`"0.46 J/(g K)"`

Explanation:

• Specific Heat capacity: Amount of heat required to raise the temperature of 1 kg substance by 1°C. Units: J/(g K)
• Molar Heat capacity: Amount of heat required to raise the temperature of 1 mol substance by 1°C. Units: J/(mol K)

They’re related as...

`"Specific Heat capacity" = "Molar Heat capacity"/"Molar mass"`

`color(white)("Specific Heat capacity") = ("24 J / (K" cancel"mol"")") /("52 g"//cancel"mol")`

`color(white)("Specific Heat capacity") = 0.46\ "J/(g K)"`
