2.7 Useful Formulas and Values
Оглавление1 Ideal gas law:PV = nRTwhere: P = pressure in atmospheres (atm)V = volume in liters (l)n = number of moles of gasR = 0.0821 (l) (atm) (mol−1) (K−1)T = temperature in K
2 Volume of 1 mole of CO2 under standard conditions = 22.40 l.
3 Standard temperature and pressure for gases: T = 273 K; P = 1 atm.
4 Baking soda content of baking powder: 28% NaHCO3 (w/w).
5 Formula weight of NaHCO3 = 84.01.
6 Molecular weight of CO2 = 44.0.
