The following data have been taken from the CRC Handbook. Some of the values may be different from those in the textbook.
For atomic masses, use the Periodic Table.
General Information:
Avogadro's number = 6.022045 x 1023/mol Gas constant, R = 8.314 kPa L/mol K
Specific heat of water = 4.184 J g- 1 oC - 1 = 8.314 J/mol K
= 0.08206 L atm/mol K
