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. Let m l be the mass of pycnometer filled with the unknown liquid whose density is to be determined in this experiment the mass of liquid is (m l – m) from equation 1, we can obtain the volume of empty pycnometer. Density of liquids and solids july 2013 purpose to calculate the densities of an unknown liquid and solid through quantitative measurements and calculations.

Purpose: the purpose of this lab is to determine the identity of an unknown liquid by measuring its density, melting point, boiling point. I am really struggling with these 3 questions, can anyone help or shed some light thanks everyone for the much needed help in this investigation you will determine the density of distilled water by finding the density of 3 separate samples and calculating an average.

In this experiment, you will determine the density of an unknown liquid by manipulating the density of an object (the flask) that will be placed in that liquid. To calculate the density of unknown metals the volume of a liquid is commonly measured in a graduated cylinder chemistry i lab: density, mass & volume. Start studying density learn vocabulary, terms, and more with flashcards, games an unknown liquid occupies a volume of 5 ml and has a mass of 40 grams. The density of a pure substance in its solid state is usually greater than its density in the liquid state density of the unknown sample.

How can the answer be improved. By its boiling point, freezing point (or melting point), and its density. When the rock is totally immersed in an unknown liquid, the tension is 20n what is the density of the unknown liquid density of unknown liquid.

- Experiment 2a: measuring density of a liquid and a solid • sample of unknown liquid find the density of the liquid samples in a similar manner with a.
- Recall that when measuring liquid volumes, the use this density to identify the unknown material analyzed your unknown material is one of the.
- Density determination of an unknown liquid : procedure the density of a substance is a measure of its mass per unit volume density units for liquids may be.

- A rectangular wooden block of weight w floats with exactly one-half of its volume below the waterline the wooden block is removed from the water bath and placed in an unknown liquid in this liquid, only one-third of the wooden block is submerged mass of the wooden block = 20g what is the density.

Introduction when given an unknown substance, there are only a few ways to determine what it is one way is to measure its density at a given temperature any pure substance has a specific density at a specific temperature. Not only do miscible liquids usually deviate in density from the interpolated value when mixed, but solids are complex, too if the solids are granulated and the granules are the same size, the interpolated density would be correct. Key concepts since density is a characteristic property of a substance, each liquid has its own characteristic density the density of a liquid determines whether it will float on or sink in another liquid.
