3. if a graduated cylinder had a mass of 100 g and contained a liquid in which the combined mass was 120 g and a volume of 25 ml, then what is the mass of the liquid? what is the density of this liquid? would it be able to float on water? 4. if a graduated cylinder had a mass of 25 g and contained a liquid that had a combined mass of 60 g and a volume of 10 ml, then what is the mass of the liquid? what is the density of this liquid? would it be able to float on water?

Answer

Explicación:

Paso 1: Encontrar la masa del líquido en el problema 3

Restamos la masa del cilindro graduado de la masa combinada. $m_{líquido}=120\ g - 100\ g = 20\ g$

Paso 2: Calcular la densidad del líquido en el problema 3

Usamos la fórmula $\rho=\frac{m}{V}$, donde $m$ es la masa y $V$ es el volumen. $\rho=\frac{20\ g}{25\ mL}=0,8\ g/mL$ Para determinar si flota en agua, comparamos con la densidad del agua ($\rho_{agua} = 1\ g/mL$). Como $0,8\ g/mL<1\ g/mL$, sí flota.

Paso 3: Encontrar la masa del líquido en el problema 4

Restamos la masa del cilindro graduado de la masa combinada. $m_{líquido}=60\ g - 25\ g = 35\ g$

Paso 4: Calcular la densidad del líquido en el problema 4

Usamos la fórmula $\rho=\frac{m}{V}$. $\rho=\frac{35\ g}{10\ mL}=3,5\ g/mL$ Para determinar si flota en agua, comparamos con la densidad del agua ($\rho_{agua}=1\ g/mL$). Como $3,5\ g/mL > 1\ g/mL$, no flota.

Respuesta:

  1. Masa del líquido: 20 g, Densidad: 0,8 g/mL, Flota en agua: Sí
  2. Masa del líquido: 35 g, Densidad: 3,5 g/mL, Flota en agua: No
