An empty graduated cylinder has a mass of 42.91 g. When filled with 40.00 mL of an unknown liquid, it has a mass of 103.26 g. Calculate the density of the unknown liquidz

Respuesta :

Answer:

1.511g/mL

Explanation:

To find density, we can use the equation

[tex]d=\frac{m}{V}[/tex]

We have V (40mL) To find m (mass), we must subtract as such:

[tex]103.36-42.91=60.45[/tex]

60.45 grams is the mass of the unknown liquid.

Now, we plug the values we have into the density equation.

[tex]d=\frac{60.45g}{40.00mL} \\\\ d=1.511\frac{g}{mL}[/tex]

The density of the unknown liquid is 1.51 g/mL

Density can be defined as the mass of an object per unit volume of the object.

[tex]Density = \frac{mass}{volume}[/tex]

To solve the question given above, we'll begin by calculating the mass of the unknown liquid. This can be obtained as follow:

Mass of empty cylinder = 42.91 g

Cylinder + unknown liquid = 103.26 g

Mass of unknown liquid =?

Mass of unknown liquid = (Cylinder + unknown liquid) – (Mass of empty cylinder)

Mass of unknown liquid = 103.26 – 42.91

Mass of unknown liquid = 60.35 g

Finally, we shall determine the density of the unknown liquid. This can be obtained as follow:

Mass of unknown liquid = 60.35 g

Volume of unknown liquid = 40 mL

Density of unknown liquid =?

Density = mass / volume

Density = 60.35 / 40

Density of unknown liquid = 1.51 g/mL

Therefore, the density of the unknown liquid is 1.51 g/mL
