In determining the density of a liquid a student left air bubbles trapped in the volumetric pipet Did this give a density less than expected or greater than expected why?

Well the air bubbles contrain a element called SW (short for swag). When swag is produced during a density excitement, the results vary. Usually results favor swag. To get around this trouble, you must not produce swag! To do this, dress like a hill billy, get rid of your friends, and make sure to tell everyone you meet to "f*** off". Once swag is not produced in the density experiment, you will receive the true density results! Pure Density.

Thus in the calculation density = mass/volume the denominator is increased by the volume of the bubbles and when you increase the denominator of a fraction the value of the fraction decreases. Thus the density you obtain from this calculation is too small.

What is the unit of volumetric density?
Volumetric density is the density based upon the volume of an object.
What affect will water on the outside of the flask have in determining the density?
The density is lower.
What is direct calibration?
volume of water delivered by a buret or pipet, or contained in a volumetric flask, is obtained directly from weight of the water and its density
What solvent used to determine the density of diphenyl?
Toluene, benzene, or hexane are suitable organic solvents for determining the density of diphenyl.
Mass per unit volume?
The density, or the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is p (the lower case Greek letter rho).Density is calculated as mass divided by volume: p = m/v
What is the unit of volumetric density?
Volumetric density is the density based upon the volume of an object.
What is air density and volumetric mass in A-10 thunderbolt II?
the air density is 40,000
How does the temperature and density play a role in calibration of glassware?
Glassware for volumetric measurements (pipettes, burettes, volumetric flasks etc.) are calibrated at 20 oC.
What is the formula for determining density?
Density = Mass/ Volume
What is the difference between mass flow and volumetric flow?
volumetric flow meter are used in application where density changes,it means volume of the substance is changing.For e.g. in natural gas pipe line pressure varies,so as the density.
What are the causes of reduced volumetric efficiency?
Reduction in power density. Power density is the power produced by the engine per volume unit. Reduced volumetric efficiency means that less air/fuel will be delivered to the engine for a specific engine volume.
What affect will water on the outside of the flask have in determining the density?
The density is lower.
What is the density of bubbles?
blah blah blah
What is the purpose of determining average density?
science
How does carbonation effect density?
The air bubbles lower the density of the solution
Why do vapor bubbles rise to surface when a liquid is boiling?
Since the bubbles have less density than the surrounding water, gravity pulls the water down, and the bubbles go up.
What is direct calibration?
volume of water delivered by a buret or pipet, or contained in a volumetric flask, is obtained directly from weight of the water and its density
