What can be used to identify an unknown substance?
Calculating density.
When measuring the Volume of a solid object, what unit is it usually expressed in? What is the formula?
In cubic centimeters. Length x width x height
22.95g / 15.45cm3. Find density. Say if it sinks or floats.
1.49g/cm3. The object sinks.
What are the two units of measurement for density?
g/cm3 and g/mL
What kind of substance property is Density?
A Physical Property
Name two ways density is important to understand (what can it help us determine).
To figure out if an object sinks or floats in water,& can help us identify unknown substances.
An object has the Density of 12.36 g/mL and the Mass of 6.52 g. What is the Volume?
0.528 mL
97g / 105mL. Find the density. Say if it sinks or floats.
0.92g/mL. This object floats.
