Answer: Divide the mass of the object by its volume to yield the density of the object. For example, the object density = mass / (Vf – Vi). Compare the measured density to that of pure gold (19.3 g/cc) to determine whether the object is made of pure gold.
Explanation: I searched it
Basically, the graph shows a linear (line) relationship with mass and volume. The slope will equal the density of the substance because mass/volume is the equation for density. Your paper is a bit unclear, but I can understand this much, Hope this helped a little bit :)
Atomic number = 127 – 53=74 neutrons
Answer:
B. It is highly flammable.
Explanation:
Chemical properties deal with how the substance will behave when brought into contact with other substances, and usually have to do with it undergoing some kind of reaction. Flammability is a chemical property.
Density, melting point, and color are all considered physical properties.
