# What are sources of errors in the density experiment?

## What are sources of errors in the density experiment?

The most common reasons for density errors include using the wrong or inaccurate instruments and not accounting for temperature changes.

• The Liquid Volume.
• Regular Solid Volume.
• Irregular Solid Volume.
• The Temperature Effects.
• Mass and Other Considerations.

What are the 2 variables needed to determine the density of a substance?

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.

What is the percentage error in determining the density of water?

The percent error of your density calculation is 2%.

### How to measure the density of an unknown liquid?

The best and simple approach to measure density of an unknown liquid is to measure its mass by any approach and then to divide it by its volume. Just note down the numerical values provided and you can solve the question putting these specific values in the formula of density.

How is the density of an unknown seed determined?

The density of an unknown seed will be determined using the displacement of water. A thermometer and volumetric pipette will be calibrated and be used to experimentally determine the density of liquid water, which will be compared to the literature value with appropriate error analysis.

How is the density of a substance determined?

The SI unit of density is always expressed in the unit of kg m -3 or g cm -3. As the temperature increases, the density of a substance will be decreased, this will be discussed later in discussion. When thermal expansion occurs, the volume of the substance increases while its mass is remained.

## How is the mass of water in a pycnometer determined?

The mass of the dry and empty pycnometer is represented by M and M W be the mass of the pycnometer filled with water at t°C. The mass of water in the pycnometer at this tempearature will be determined by using mass of pycnometer, M W minus mass of empty pycnometer, M.
