Calculate the density of M&M’s given the following data:

Mass of 250.0 mL beaker = 197.816 g

Mass of beaker and 20 M&M’s = 342.816 g

Volume of water in graduated cylinder = 8.0 mL

Volume of water in graduated cylinder and 10 M&M’s = 18.5 mL (Points : 3)

342.816 g = mass beaker + 20 M&M

-197.816 g = mass beaker
--------
?? = mass 20 M&Ms
mass of 10 M&Ms = ?

18.5 mL = volume M&Ms + water.
-8.0 mL = volume H2O
------------
? = volume 10 M&Ms

density = mass 10 M&Ms/volume 10 M&Ms

I should point out a problem here if you aren't aware of it already; M*Ms are soluble in water. Therefore, the density can't be determined this way.

To calculate the density of M&M's, we need to use the formula: density = mass/volume.

First, let's calculate the mass of 20 M&M's:
Mass of beaker and 20 M&M's - Mass of 250.0 mL beaker = 342.816 g - 197.816 g = 145 g.

Now, let's calculate the volume of 10 M&M's:
Volume of water in graduated cylinder and 10 M&M's - Volume of water in graduated cylinder = 18.5 mL - 8.0 mL = 10.5 mL.

Now, we can calculate the density of M&M's:
density = mass/volume = 145 g / 10.5 mL = 13.81 g/mL.

Therefore, the density of M&M's is 13.81 g/mL.

To calculate the density of M&M's, we need to determine the mass of M&M's and the volume they occupy.

1. First, let's calculate the mass of 20 M&M's by subtracting the mass of the empty beaker (197.816 g) from the mass of the beaker with 20 M&M's (342.816 g):

Mass of 20 M&M's = Mass of beaker and 20 M&M’s - Mass of empty beaker
= 342.816 g - 197.816 g
= 145.0 g

2. Next, let's calculate the volume of 10 M&M's. Since we're given the volume of water in the graduated cylinder with 10 M&M's, we can calculate the volume difference before and after adding M&M's:

Volume of 10 M&M's = Volume of water in graduated cylinder and 10 M&M’s - Volume of water in graduated cylinder
= 18.5 mL - 8.0 mL
= 10.5 mL

3. Finally, we can calculate the density of M&M's using the formula:

Density = Mass / Volume

Density of M&M's = Mass of M&M's / Volume of M&M's
= 145.0 g / 10.5 mL
≈ 13.81 g/mL

Therefore, the density of M&M's is approximately 13.81 g/mL.
