Calcular el tanto por ciento en masa de una disolución que tiene 25 ml de un soluto con una densidad de 0.8 g / cm3, y 500 ml de disolvente con una densidad de 1.1 g / cm3

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

C) the increase in atmospheric pressure pushes the walls of the balloon outward thus making it  is the answer.hope i you.
