Question

encontrar la masa molecular
N2 O3
H2SO4
H2CLO3
H2PO4
A2 O3

Answer 1

Respuesta:

Mm N2O3: 76 g/mol

Mm H2SO4: 98 g/mol

Mm H2ClO3: 85.5 g/mol

Mm H2PO4: 97 g/mol

Mm Al2O3: 102 g/mol

Explicación:

N2O3

N: 2 x 14 = 28 g/mol

O: 3 x 16 = 48 g/mol

      Mm = 76 g/mol

H2SO4

H: 2 x 1 = 2 g/mol

S: 1 x 32 = 32 g/mol

O: 4 x 16 = 64 g/mol

       Mm = 98 g/mol

H2ClO3

H: 2 x 1 = 2 g/mol

Cl: 1 x 35.5 = 35.5 g/mol

O: 3 x 16 = 48 g/mol

       Mm = 85.5 g/mol

H2PO4

H: 2 x 1 = 2 g/mol

P: 1 x 31 = 31 g/mol

O: 4 x 16 = 64 g/mol

       Mm = 97 g/mol

Al2O3

Al: 2  x 27 = 54 g/mol

O: 3 x 16 = 48 g/mol

       Mm = 102 g/mol
