Question

Gente, acham a massa molecular;

CO4
HNO2
Ba(OH)2
Mg(Cio3)2
Be3(PO4)2
Na OH

algum inteligente??​

Answer 1

Olá!:

a ) CO₄ = ( 12 * 1 ) + ( 16 * 4  ) => 76 u

b) HNO₂ = ( 1 * 1 ) + ( 14 * 1 ) + ( 16 * 2 ) => 47 u

c) Ba(OH)₂  = ( 137,32 * 1 ) + ( 16 * 2 ) + ( 1 * 2 ) => 171,32 u

d) Mg(ClO₃)₂ =  ( 24 * 1 ) + ( 35,5 * 2 ) + ( 16 * 6 ) => 191 u

e ) Be₃(PO₄)₂ = ( 27,03 * 1 ) + ( 31 * 2 ) + ( 16 * 8 ) => 217,03 u

f ) NaOH = ( 23 * 1 ) + ( 16 * 1 ) + ( 1 * 1 ) => 40 u

Espero ter ajudado!
