un matraz volumétrico se llena hasta la marca de 25,0ml con alcohol etílico. el matraz se pesa antes y después de introducir el alcohol por lo que se determina que contiene 19,7325g de este liquido, en un segundo experimento, se introduce 25,0920g de balines de metal al matraz y este se llena nuevamente hasta la m arca de 25,0 ml con alcohol etílico se determina la masa total del metal mas el alcohol en el matraz la cual es de 38,4704g. cual es la densidad del metal en g/ml?
