In order to determine the density of a liquid, an experimenter collected the following data: Mass of an empty graduated cylinder: 27.3g. Mass of cylinder and 10.0 mL of liquid X: 35.2g. Calculate the experimental density of liquid X.

Respuesta :

Answer : The experimental density of liquid X is, 0.79 g/ml

Solution : Given,

Mass of an empty graduated cylinder = 27.3 g

Mass of cylinder and mass of liquid X = 35.2 g

Volume of liquid X = 10 ml

First we have to calculate the mass of liquid X.

Mass of cylinder + Mass of liquid X = 35.2 g

Mass of liquid X = 35.2 g - Mass of cylinder

Mass of liquid X = 35.2 g - 27.3 g = 7.9 g

Now we have to calculate the density of liquid X.

Formula used for density :

[tex]\text{Density of liquid X}=\frac{\text{Mass of liquid X}}{\text{Volume of liquid X}}[/tex]

Now put all the given values in this formula, we get the density of liquid X.

[tex]\text{Density of liquid X}=\frac{7.9g}{10ml}=0.79g/ml[/tex]

Therefore, the experimental density of liquid X is, 0.79 g/ml
