The share price should be one dollar times 19.4 which is the average P/E ratio in this industry, so the share price should be $19.4, and the company value should be $19.4 million. So, you should pay less than $19.4 million.

2020-10-1The CF 4 -adsorption uptake was dictated by the specific surface area and pore volume of narrow micropores less than 0.9 nm in diameter. PET-K (2)700, which was developed by KOH activation at 700 &C and KOH/carbon mass ratio of 2, showed the highest CF 4 -adsorption uptake of 2.43 mmol g −1 at 25 &C and 1 atm.

Gas Phase Heat Capacity (Shomate Equation) Cp& = A + B*t + C*t2+ D*t3+ E/t2. H& − H&298.15= A*t + B*t2/2 + C*t3/3 + D*t4/4 − E/t + F − H. S& = A*ln(t) + B*t + C*t2/2 + D*t3/3 − E/(2*t2) + G. Cp= heat capacity (J/mol*K) H& = standard enthalpy (kJ/mol) S& = standard entropy (J/mol*K) t = temperature (K) / 1000.
