Question

Calcule as massas molares dos compostos abaixo:
a) Al2(Oh)3
b) Mg2(SO4)3
C)Si5(OH)3
D)Ca2(O2H5)3
E)NH4(no3)2

Answer 1

Resposta:

a) Al2(Oh)3= (2.27g+3.16g+3.1g)= 105g/mol

b) Mg2(SO4)3= (2.24g+3.32g+12.16g)=336g/mol

C)Si5(OH)3=(5.28g+3.16g+3.1g)=191g/mol

D)Ca2(O2H5)3=(2.40g+6.16g+15.1g)=191g/mol

E)NH4(no3)2=(1.14g+4.1g+2.14g+6.16g)=142g/mol
