This depends on the nature and form of the sample:
- for a solid with a regulate shape weight the sample and calculate the volume from the dimensions; density is the ratio between mass and volume. You can measure the volume of great sample by water displacement.
- for other solids use a pycnometer
- for liquids use a densimeter (simple or electronic)
etc.

You can find the density of an unknown liquid without measurement tools by dividing its mass by its volume.
Hydrometer and trial glass.
Density equals mass divided by volume. your given examples density is .902g/cm^3. (cm^3 is interchangeable with mL) the density of this unknown liquid is close to that of water (.997g/mL) and I therefore believe it is water.
The density is mass/volume = 30.6g/53.3ml = 0.5741 grams per millilitre.
Problem: You are given two unknown liquids. Find the density of each. Materials: 100ml graduated cylinder, triple beam balance, calculator, 2 unknown liquids. Procedure: 1) Find the mass of the empty graduated cylinder. 2) Pour unknown liquid #1 into the graduated cylinder to the 50 ml. level. 3) Find the mass of the graduated cylinder with 50ml of unknown liquid #1. 4) Repeat steps 1-3 for unknown liquid #2. We can calculate density of a liquid using the formula: Density= Mass/Volume where mass is that for just the liquid (you must subtract out the mass of the graduated cylinder). Now let's calculate the densities of the two liquids using the following given data. Liquid #1: Given: Mass of empty graduated cylinder = 78 grams Mass of graduated cylinder with unknown liquid #1= 128 grams. Find: a) Mass of just the liquid = ____ b) Volume of liquid=_____ c) Density of liquid #1 =____ Liquid #2: Given: Mass of empty graduated cylinder = 78 grams Mass of graduated cylinder with unknown liquid #2= 117.5 grams. Find: a) Mass of just the liquid = ____ b) Volume of liquid =_____ c) Density of liquid #2=____ Check your answers by inserting the value in the box below.
Mass of unknown liquid = 142.01 g - 105.56 g = 36.45 gVolume of unknown liquid = 45.5 mldensity = mass/volume = 36.45 g/45.5 mldensity = 0.801 g/ml
Isn't it just 800 grams?
how would you find the density of an unknown liquid if you have all of the equipment of the laboratory equipment you need?

The liquid's density is 0.8 g/mL
A lab balance.
A gram is a measure of mass, not of weight. The density of the liquid is 0.8 grams per mL.
Density equals mass divided by volume. your given examples density is .902g/cm^3. (cm^3 is interchangeable with mL) the density of this unknown liquid is close to that of water (.997g/mL) and I therefore believe it is water.
A graduated cylinder is a piece of laboratory equipment used to measure the volume of a liquid and are generally more accurate and precise than laboratory flasks and beakers.
density is = mass over volume so... use a scale to get mass and a graduated cylender to get volume. If you find yourself in a lab there is equipment to find the density strait away.

Laboratory equipment is not needed to decant a mixture because one liquid is denser than the other liquid so they separate naturally; one rising to the top and the other sinking toward the bottom.
