DNA and rna are both nucleus acids
Atoms that satisfy the octet rule are said to be INERT
For this case, we use the equation for an ideal gas which is expressed as PV=nRT where P is the pressure, V is the volume, n is the number of moles and T is the temperature. We calculate as follows:
PV = nRT
T = PV / nR
T = 20 kPa (100 L) / 1 mol (8.314)
T = 240.56 K
