Question

Oblicz masy cząsteczkowe :
K2O

ZnS

tlenku fosforu (V)

Answer 1

 

 

tlenek fosforu (V) -

 

Answer 2

mK2 = 2 razy 39 u

mO = 16 u

mK20 =mK2 + mO = 78 u + 16 u = 94 u

 

mZn = 65 u

mS = 32 u

mZnS = mZn +mS = 65 u + 32 u = 97 u

 

mP4 = 4 razy 31 u = 124 u

m010= 10 razy 16 u = 160 u

mP4010 = mP4 + m010 = 124 u + 160 u = 28s u
