Compute the specific heat capacity at constant volume of nitrogen (N2) gas. The molar mass of N2 is 28.0 g/mol.
goldfiish [28.3K]

Answer:Specific heat capacity at Constant volume of Nitrogen =742.32JKg.K

Explanation:

The Specific heat capacity at Constant volume of an ideal gas is given as

c =Cv / M

Cv= Constant volue of gas

M= Molar mass

But  First, we determine the Constant volume, Cv  which is given as

Cv = 5/2R since Nitrogen is a diatomic gas, N2 where R= 8.314Jmol.k

= 5/2 x 8.314Jmol.K

=20.785Jmol.K

Specific heat capacity at Constant volume, c

c= Cv/M

M=molar mass = 28.0 g/mol.

changing to kg/mol =28/1000= 0.028kg/mol

Therefore c =20.785Jmol.K/0.028kg/mol

=742.32JKg.K

Why are all molecules not compounds?
Elena-2011 [213]

Answer:

Explanation:

All compounds are molecules, but not all molecules are compounds. That is because a molecule can be made up of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule. However, all compounds are made up of two or more different types of atoms.
