Question

cati moli din fiecare substanta se gasesc in 10 grame de H2O 2O de grame de NH3 si 10 grame de HCL va rog

Answer 1

MH2O=2+16=18

18 g H2O--------------1 mol H2O

10 g H2O------------X

X=10:18=0,55 moliH2O

MNH3=14+3=17

17 g NH3---------1 mol NH3

20 g NH3--------X

X=20:17=1,17 moliNH3

MHCl=1+35,5=36,5

36,5 g HCl-------------1molHCl

10 gHCl-------------------x

x=10:36,5=0,27 moliHCl
