Rekenmachine
Algemeen
Het is de bedoeling de vragen zonder rekenmachine op te lossen.
√2 = 1,41 en √3 = 1,73, log(2) = 0,30 en log(3) = 0,48
Constanten en formules
Algemene gaswet: p * V = n * R * T
Molair gasvolume bij 273 K en 1013 hPa: 22,41 L
Molaire gasconstante: R = 8,31 J/(K*mol)
Omrekening graden kelvin – graden celsius:
T = 0 K dan θ = -273 oC
Massa elektron: me = 9,10 * 10-31 kg
Massa proton: mp = 1,67 * 10-27 kg
Massa neutron: mn = 1,67 * 10-27 kg
Getal van Avogadro: NA = 6,02 * 1023
π = 3,14 √2 = 1,41 log 2 = 0,30
log 3 = 0,48 log 5 = 0,70
e = 2,72 ln 2 = 0,69 ln 3 = 1,10 ln 5 = 1,61
