A 45.3 g sample is placed in a graduated cylinder causing the water level to rise from 25.0 mL to 41.8 mL. Calculate the density.

45.3g/(41.8-25.0)mL = 2.696 g/mL

Well, let me be your chemistry comedian for a moment!

So, you have a sample that made the water level rise in the graduated cylinder. Looks like it really wanted to make a splash!

To calculate the density, we can use the formula: density = mass/volume. The mass of the sample is 45.3 g and the volume change in the water level is 41.8 mL - 25.0 mL = 16.8 mL.

Now, we need to convert the volume from mL to liters because density is typically expressed in g/mL or g/cm³. Since we know that 1 mL is equal to 1 cm³, we can say that 16.8 mL = 16.8 cm³.

Therefore, the density of the sample is 45.3 g/16.8 cm³.

And the final punchline?

The density is approximately 2.70 g/cm³!

To calculate the density, you need to know the mass and volume of the object.

The given mass of the object is 45.3 g.

To calculate the volume, you subtract the initial volume of the water (25.0 mL) from the final volume of the water (41.8 mL):

Volume = Final volume - Initial volume
Volume = 41.8 mL - 25.0 mL
Volume = 16.8 mL

However, since the density is typically expressed in grams per milliliter (g/mL), we need to convert the volume to milliliters (mL) to get the correct units:

Volume = 16.8 mL = 16.8 cm^3

Now, we can calculate the density:

Density = Mass / Volume
Density = 45.3 g / 16.8 cm^3

Therefore, the density of the sample is approximately 2.7 g/cm^3.

To calculate the density of the sample, we need to use the formula:

Density = Mass / Volume

First, we need to calculate the volume of the sample by finding the difference in water level before and after placing the sample in the graduated cylinder. The initial volume (V1) is 25.0 mL, and the final volume (V2) is 41.8 mL.

Volume = V2 - V1
Volume = 41.8 mL - 25.0 mL
Volume = 16.8 mL

Note: It is important to convert all measurements to the same unit before performing calculations. Here, the units for volume and mass are already in milliliters (mL) and grams (g) respectively, so no conversion is needed.

Now that we have the volume (16.8 mL), we can calculate the density.

Density = Mass / Volume
Density = 45.3 g / 16.8 mL

Finally, we can find the density:

Density = 2.696 g/mL

Therefore, the density of the sample is 2.696 g/mL.
