Answer:

La respuesta está en la explicación

Explanation:

Al realizar este análisis, el químico estará obteniendo la masa que la sustancia desconocida ocupa en un volumen determinado, a esto se le conoce como La Densidad de la Sustancia.

La densidad se puede definir como la masa (En gramos) que pesa una sustancia que ocupa 1mL. Así, la densidad de esta sustancia será:

0.856g/mL es la densidad de esta sustancia

Ahora, debes identificar en la tabla, cuál sustancia tiene una densidad similar a la obtenida y, de esta manera, podrías saber a cuál sustancia corresponde.
