A rock has a mass of 127 g and displaces 32.1 mL of water. What is the density of the rock?

density=mass/volume watch units.

3.956

Oh, density... you could say it's the rock's way of being "dense" or, in other words, how tightly packed the particles are. Let's crunch the numbers here.

First, we have the mass of the rock, which is 127 grams. And then we have the volume, which is 32.1 milliliters.

So, we just need to divide the mass by the volume to get the density. I know, I know... math can be "dense" sometimes, but don't worry, I've got your back.

Now, let's do some math magic. *waves wand*

127 grams divided by 32.1 milliliters... and abracadabra!

The density of the rock is approximately 3.95 grams per milliliter. Ta-da!

To find the density of the rock, you need to divide the mass of the rock by the volume it displaces.

Given:
- Mass of the rock = 127 g
- Volume displaced by the rock = 32.1 mL

However, it is important to note that density is typically expressed in units of grams per milliliter (g/mL) or grams per cubic centimeter (g/cm³).

So, to calculate the density of the rock, divide the mass by the volume:

Density = Mass / Volume

Density = 127 g / 32.1 mL

However, since the units of mass and volume do not match, we need to convert the volume from milliliters (mL) to grams (g).

Since 1 mL of water has a mass of 1 gram, we can simply treat the volume of water displaced (32.1 mL) as being equivalent to 32.1 g.

Density = 127 g / 32.1 g

Density ≈ 3.96 g/mL

Therefore, the density of the rock is approximately 3.96 grams per milliliter (g/mL).

To find the density of the rock, we need to divide its mass by its volume. The given mass of the rock is 127 g, and the volume of water it displaces is 32.1 mL.

1. Start by converting the volume from milliliters (mL) to grams (g), since both mass and volume need to be in the same unit for the density calculation.

1 mL of water is equal to 1 g. So, the volume of water displaced by the rock is already in grams.

2. Now that both mass and volume are in grams, we can calculate the density.

Density = Mass / Volume

Density = 127 g / 32.1 g

Density ≈ 3.95 g/mL

Therefore, the density of the rock is approximately 3.95 grams per milliliter (g/mL).
