Koliko grama K2CO3 x 2H2O i 16,5%tne HCl ,treba za razvijanje 28,4 dm3 CO2 ( 22 stepeni celzijusa i 100 312 Pa)
M( K2CO3 x 2H2O) = 126,0 g/mol
M(HCl)= 36.5 g/mol
Gustina (16,5 % tne HCL) = 1.08 kg/dm3
M(CO2) = 44 , 00 g/mol
Jednacina reakcije: K2CO3 + 2HCl -->2KCl+H2O+CO2
Kolicinu CO2 odredices preko jednacine: pV=nRT.
