What you really need to know is the mass of the liquid. You'll most likely measure it

by weighing the liquid when it's in the container. The weight you measure will include

the weight of the container, and you'll have to subtract that away in order to know

the weight of the liquid alone.

If you can figure out a way to weigh the liquid when it's out of the container, then

you'll never need to do anything about the mass of the container, not even measure it.

Density isn't a "better" measurement, "better" is a subjective term, but it is more efficient because density encompasses measurements of both volume and mass. That's why it is expressed as "grams per cubic centimeter" or "kilograms per meter." It is literally the mass divided by the volume.

Because when you want to measure the weight of some liquid inside the

cylinder, you put the whole thing on the scale, but the weight you read

off the scale is not the weight of the liquid. It's the combined weight of

the liquid PLUS the weight of the cylinder. In order to know the weight

of the liquid alone, you have to take away the weight of the cylinder,

and THAT'S why you need to know what the cylinder weighs before you

pour liquid into it.

The definition of density is: (mass) divided by (volume). It's going to be pretty tough

to determine the sample's density if you don't figure out some way to find its mass.

### Why do you first need to measure the mass of the graduated cylinder when it is empty?

Measuring the mass of the graduated cylinder when it is empty allows you to determine the tare weight of the cylinder. This tare weight can then be subtracted from the total weight when the cylinder is filled with a substance to accurately measure the mass of just the substance.

### What is the first thing you have to determine when using a graduated cylinder?

The first thing you have to determine when using a graduated cylinder is the volume of liquid it can hold and the smallest volume increment it can measure. This helps ensure that you are using the appropriate graduated cylinder for your measurements and that you are able to read the volume accurately.

### Why must you first find the mass of a graduated cylinder alone when finding the density of a liquid?

If you are going to weigh a liquid in a graduated cylinder, the weight that you will get when you place the cylinder on the scale will be the combined weight of the cylinder and its contents. To find the weight of the contents alone, you therefore have to subtract the weight of the empty cylinder. And to calculate density you need to know both the weight and the volume.

### How do you measure accurately with a graduated cylinder?

First, fill it up with water and write down the number it is at. Then drop the item that you wish to measure with. And subtract the two numbers that you get.

### What is use of graduated cylinder?

A graduated cylinder is used for measuring the Volume of different things such as irregular objects. It uses the unit ml. It has a miniskus FYI that is when you use water and if you look closely you can see it curve at the top. You measure the miniskus a the bottom of the Curve. Also to find the Volume of an irregular object you first measure the water (starting volume) then place the Object in it and you will have your ending volume. then subtrct the difference from the starting volume and the ending and you will have your volume in ml.

### How do you measure the volume of an object that was NOT a rectangular prism?

One way to measure the volume of an irregular object is to use a graduated cylinder. Fill the cylinder about half-way with water, and measure the volume. Then, place the object in the cylinder and measure the new volume. Subtract the first from the second to find the change in volume of the water. This change in volume is the voume of the object. Unfortunately, this method will not work for all objects as some are to large to fit in a graduated cylinder and some will dissolve in water, but it is very usefull in most situations.

### How can you find the density of a liquid using a graduated cylinder?

Density of an object is defined as mass per unit volume. Density - mass/volume (m/v) To find the density of a liquid using a graduated cylinder, you first of all take a measurement of the mass of the empty graduated cylinder (m1) and write it down. Lets say the mass is 0.5 kg (500 grams) Then fill the cylinder with the liquid that you want to find the density for and note down the volume (v). For easier calculation take 1 liter of the liquid. Now take a measurement of the mass of the cylinder with the liquid (m2) in it and write it down. Subtract the mass of the empty cylinder from the mass of the cylinder and liquid combined to get the mass of the liquid (m = m2 - m1). Now divide the result z by the volume (v) of the liquid. density = m/v

### What measure tool do you use to measure objects?

To measure the mass on an irregular object, you can use Water Displacement.Water displacement is a way of measuring mass. Materials needed for this are:A graduated cylinderWaterVariable (Irregular Object).Fill the graduated cylinder with a certain amount of water. Memorize it.Put the irregular object into the graduated cylinder. Find the mass by subtracting the first amount of water from the second. That's your mass.Hope this helps, and sorry if you didn't need all this information!

### Albert Einstein invented the first graduated cylinder in what year?

Albert Einstein did not invent the first graduated cylinder. Graduated cylinders have been used in scientific experiments and measurements since the early 19th century, before Einstein was born.

### How can you calculate the volume of an irregularly shaped object?

One way to calculate the volume of an irregularly shaped object is by using the water displacement method. Submerge the object in a known volume of water and measure the change in volume to determine the object's volume.

### How does a piece of metal in a graduated cylinder of water allows you to figure out the volume?

The reading on the graduated scale is taken before and after the metal is lowered into the cylinder . The second reading is subtracted from the first. This gives the volume of the metal in cubic centimetres.
