Question

cálculo de massa molar de a)H²CO³ b)SO² c) Mg (NO³) 2 d) Na (OH) 2

preciso para hj pfv ​

Answer 1

Olá!:

a ) H₂CO₃ = ( 1 x 2 ) + ( 12 x 1 ) + ( 16 x 3 ) => 62 g/mol

b) SO₂ = ( 32 x 1 ) + ( 16 x 2 ) => 64 g/mol

c) Mg(NO₃)₂ = ( 24 x 1 ) + ( 14 x 2 ) + ( 16 x 6 ) => 148 g/mol

d) Na(OH)₂ = ( 23 x 1 ) + ( 16 x 2 ) + ( 1 x 2 ) => 57 g/mol

Espero ter ajudado!
