Obliczyć stężenie molowe 12% roztworu chlorku amonu o gęstości 1,03g/cm3
Cp * d= Cm * M * 100% Cp= 12% d= 1,03g/cm3 M NH4Cl= 53g/mol Cm= ? Cm * M * 1% = Cp * d * 10 Cm * 53g/mol * 1% = 12% * 1,03g/cm3 * 10 Cm = 12 * 1,03 * 10/ 52* 1 Cm= 2,33 [mol/dm3] Pozdrawiam, kate66 ;)

Cp * d= Cm * M * 100%
Cp= 12%
d= 1,03g/cm3
M NH4Cl= 53g/mol
Cm= ?
Cm * M * 1% = Cp * d * 10
Cm * 53g/mol * 1% = 12% * 1,03g/cm3 * 10
Cm = 12 * 1,03 * 10/ 52* 1
Cm= 2,33 [mol/dm3]
