DENSITY EXPERIMENT
HOMEWORK
1. A few mls of an insoluble liquid is added to water. The density of the
insoluble liquid is 1.8 g/L. What will happen upon mixing? Which layer
will be on top?
2. Why does ice float on water?
3. What would you use to measure the mass of a solid?
4. What would you use to measure the volume of a liquid?
5. Density can be used to:
6. Is density a physical property or a chemical property?
7. A meniscus must be read at the top of the dip, the bottom of the
dip, or above the dip?

The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 32
hours and the median is 28.2 hours. Twenty-four of the families in the sample turned on the television for 17 hours or less for the week.
The 7th percentile of the data is 17 hours.
Step 2 of 5: Approximately how many families are in the sample? Round your answer to the nearest integer.

A 25.0 mL sample of a concentrated citrus fruit cordial component (e.g. for lime juice), used in the food & drinks industry, was
diluted to 250 mL in a graduated volumetric flask.
A 25.0 mL sample of this diluted solution, required, on average, 22.5 mL of a standard 0.100 molar sodium hydroxide solution
using phenolphthalein indicator for the titration end-point.

Consider the following SAS data and formula.
Volume of sample at $1%: 50.2 ml
51% = 55%
52% = 70%
Volume of SAS =
[(volume of sample at S1%) (S2% - S1%)] / 100
[(1-(S2% / 100)]
Calculate the volume of SAS needed for this experiment given this information.
