## How do you find the density of an unknown liquid?

The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid. Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter.

## What is the mass of 40 mL?

40 grams

The mass of 40 mL of water is 40 grams. Since D = m/v and mL = cm3, the density of water is 1 g/cm3. Choose a volume between 1 and 100 mL.

**What is the density of the unknown liquid?**

Now let’s calculate the densities of the two liquids using the following given data. Mass of graduated cylinder with unknown liquid #1= 128 grams….Densities for some common liquids are:

Substance | Density (gm/cu.cm) |
---|---|

>Water | 1.00 |

Cooking oil | 0.92 |

Sea Water | 1.025 |

Carbon tetrachloride | 1.58 |

### How do you find the density?

The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

### How is density measured in liquids?

To measure the density of a liquid you do the same thing you would for a solid. Mass the fluid, find its volume, and divide mass by volume. To mass the fluid, weigh it in a container, pour it out, weigh the empty container, and subtract the mass of the empty container from the full container.

**What is the mass of 50 mL?**

What is the mass of 50 mL?

50 Milliliters of Water = | |
---|---|

50.00 | Grams |

1.76 | Ounces |

0.11 | Pounds |

0.05 | Kilograms |

#### What is the mass of 20 mL of water?

What is the mass of 20 ml of water? What is the density of 20 ml of water? What is the mass of 25 ml of water?…What is the density of 20 ml of water?

1 | 0.5 g/cm 3 | 20 mL |
---|---|---|

5a | 20 mL | 13.5 g/cm 3 |

#### What are two ways to find density?

Ways to Determine Density

- Direct Measurement of Mass and Volume. When measuring liquids and regularly shaped solids, mass and volume can be discovered by direct measurement and these two measurements can then be used to determine density.
- Indirect Volume Measurement.
- Estimated Density using Archimedes Principle.
