Question

me ayudan porfavor lo necesito. doy coronita...​

Answer 1

Respuesta:

O2

Mm = 32 g/mol

m = 150 g

n = 150 g / 32  g/mol

n = 4.687  moles

Explicación:

CaCO3

Mm = 100 g/mol

m = 80 g

n = 80 g / 100 g/mol

n = 0.8 moles

KClO3

Mm = 123 g/mol

m = 110 g

n = 110 g / 123 g/mol

n = 0.894 moles

AgNO3

Mm = 169,87 g/mol

m = 90 g

n = 90 g / 169,87 g/mol

n = 0.529 moles

K2SO2

Mm = 142 g/mol

m = 40 g

n = 40 g / 142  g/mol

n = 0.281 moles
