Question

cual es el peso molecular de ácido perclorico, nitrato de magnesio y ácido selenhidrico?

Answer 1

Cual es el peso molecular de

ácido perclorico = HClO4

H: 1 x 1 = 1 g/mol

Cl: 1 x 35.5 = 35.45 g/mol

O: 4 x 16 = 64 g/mol

````````````````````````````````````````````````````

Mm = 100.45 g/mol

nitrato de magnesio = Mg(NO3)2

Mg: 1 x 24.30 = 24.30 g/mol

N: 2 x 14 = 28 g/mol

O: 6 x 16 = 96 g/mol

````````````````````````````````````````````````````````````

Mm = 148.30 g/molo

ácido selenhidrico = H2Se

H: 2 x 1 = 2 g/mol

Se: 1 x 78.96 = 78.96 g/mol

`````````````````````````````````````````````````````````````

Mm = 80.96 g/mol
