Tenemos un cuerpo de 40 g cuya densidad es 1,24 g/mL y otro objeto de 70 g con una densidad de 0,96 g/mL. Si introducimos cada uno en un recipiente con agua, ¿en qué caso subirá más el nivel de líquido?

The atomic number, or number, is the described as the number of in the nucleus of an chemical element.

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
