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.
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.
The difference between the weights (grams) of the empty cylinder, and with the liquid gives you the weight of the liquid. Divide that by 30 to get the density of the liquid in g/ml
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

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.
If you know the density of the liquid, you could just weigh the material.
A graduated cylinder is used to find the VOLUME of a liquid.
measured with a graduated cylinder
You can, but the volume will not be as accurate as using a graduated cylinder, and will probably give you an inaccurate density.
The least dense liquid is found at the bottom of the graduated cylinder, because the less dense it is, the farther it will go down in th graduated cylinder.
