Question

Temă: Calculați:- MH2 ; MCH4 ; MH2O ; MNH3 ;

-1 mol H2O ; 1 mol HCl ; 1 mol CH4 ; 1 mol O2

Answer 1

Răspuns:

Explicație:

MH2= 2 .1 =2  ------> 2g/moli

MCH4= 12+ 4=16  ------> 16g/moli

MH2O=2 +16=18 --------> 18g/moli

MNH3=14 +3=17 --------> 17g/moli

MH2O = 18g/moli---------> 1mol H2O = 18g

MHCl= 1=35,5=36,5 ------> 36,5g/moli-------> 1mol HCl = 36,5g HCl

MCH4=16----> 1 molCH4   =16  g CH4

MO2= 2.16=32------> 32g O= 1mol O2
