¿Cuál es la densidad en g / mL de un material, si 30mL tienen una masa de 6 Kg?
blsea [12.9K]
Hola!

La densidad es una magnitud intensiva, es decir, no depende de la cantidad de material. La densidad se define como la relación entre la masa y el volumen de un cierto material y comúnmente se expresa en g/mL. A partir de esta definición podemos concluir que para hallar la densidad de un material es necesario conocer su masa y su volumen para posteriormente aplicar la ecuación tal como se describe a continuación:

densidad= \frac{masa}{volumen}= \frac{6 kg}{30mL}* \frac{1000g}{1kg}=200g/mL

Entonces, la opción correcta es la C. 200 g/mL

Saludos!
