va rog calculati masa moleculara relativa: NO2,SO3,H2O,N2O5,NO,SHI

Răspuns :

NO2 = 14g/mol+ 2* 16g/mol = 14+32 = 46g/mol
SO3 = 32g/mol+3*16g/mol = 32+48 = 80g/mol
H2O = 2*1g/mol+16g/mol = 2+16 = 18 g/mol
N2O5 = 2*14g/mol + 5*16g/mol = 28+80 = 108 g/mol
NO = 14 g/mol + 16g/mol= 30g/mol
SHI = 32g/mol + 1g/mol + 127g/mol = 160g/mol
