Question

Oblicz masę cząsteczkową soli:

a) CuCO₃
b) Ni(NO₃)₂
c)(NH₄)₃PO₄

Answer 1

A) CuCO₃= 63,5 + 12+ 3*16123,5u
b) Ni(NO₃)₂= 59+ 2*14+ 6*16=183u
c)(NH₄)₃PO₄= 3*14 + 12*1 + 31+ 4*16 =149u

Answer 2

MCuCo3=1*63u+1*12u+3*16u=133u
mNi(NO3)2=1*59u+2*14u+6*16u=59u+28u+96u=183u
m(NH4)3PO4=3*14u+12*1u+1*31u+4*16u=42u+12u+31u+62u=147u
