Molaridad y Solubilidad

Post by Israel Sh »

En un recipiente se mezcla 150 mL de una solución acuosa de nitrato crómico 0,3 M, con 250 mL de una solución acuosa de nitrato de plata 0.2 M. Calcule la concentración molar de la disolución formada y los gramos de ion nitrato que se encuentra en la disolución?

English please.

Calculate first the moles of the silvernitrate and the chromium nitrate.
n = c*V
0,3 mol/l * 0,15 l = 0,045 mol and 0,2 mol/l *0,25 l = 0,05 mol
The value of nitrate of the chromium salt is 3 times larger.
0,045 mol + 3* 0,05 mol = 0,195 mol
c= n/V =0,195 mol/0,4 l = 0,4875 mol/l
mc = 0,4875 mol/l *62 g/mol =30,225 g/l
