Jaką obj, 0,5 molowego kwasu solnego nalezy dodac do wodnego roztworu amoniaku aby powstalo 26.7 g chlorku amonu?
mNH4Cl=53,5u

mHCl=36,5u

HCl + NH3*H2O---->NH4Cl + H2O

36,5g HCl-------53,5g NH4Cl

xg HCl-----------26,7g NH4Cl

x = 18,2g HCl



36,5g HCl----1mol

18,2g HCl---xmoli

x = 0,5mola


0,5mola HCl-----1dm3
0,5 - x
x = 1dm3 moje pytanie skąd jest to że 0,5 mola daje 1 dm 3 ?
