The given compounds are to be categorized as suspension or colloidal solution. Concept Introduction: Suspensions are the mixtures in which the size of particles is large and the particles are able to settle down at the bottom. Colloids are non-crystalline homogeneous substances which consist of large particles of a substance that is dispersed throughout another substance. The size of colloidal particles lies between the range of 1 × 10 3 pm to 1 × 10 6 pm . Tyndall effect is the scattering of light by suspended particles of a fluid, when a beam of light is passed through the fluid. This scattering of light can be confirmed by passing a beam of light, with the help of a laser pointer, through the fluid.

Concept Introduction:
Suspensions are the mixtures in which the size of particles is large and the particles are able to settle down at the bottom.
Colloids are non-crystalline homogeneous substances which consist of large particles of a substance that is dispersed throughout another substance. The size of colloidal particles lies between the range of 1×103pm to 1×106pm.
Tyndall effect is the scattering of light by suspended particles of a fluid, when a beam of light is passed through the fluid. This scattering of light can be confirmed by passing a beam of light, with the help of a laser pointer, through the fluid.

What is the average mass of the 10 pennies? Report your value with correct significant figures.
What is the error (uncertainty) associated with each mass measurement due to the equipment?
What is the uncertainty associated with the average value? Note that the uncertainty of the balance will propagate throughout the calculation.
What is the standard deviation of the 10 mass measurements?
Explain the difference between the propagated uncertainty and the standard deviation. Which number would you use to describe the uncertainty in the measurement?
Calculate the total mass of the pennies with associated uncertainty.
Calculate the average density of a penny based on these data. Propagate the uncertainty values for both mass and volume in your calculations.
