chemistry test review

what is the difference between the mass of an object and its volume

mass is how many particles are in a object, volume is how much space is taken

how would you represent the atoms of aluminium in the gaseous phase

they would be more free-floating and spaced out

what does the slope tell you

the relationship between the volume of water in mL vs the volume of the container in cm³

how could you account for the fact that they obtained a negative y-intercept

during the lab, when data was being collected, miscalculations or water could have been split

write the equation for the line

Mass (g) = 0.9 x Volume (mL) 

what information is given by the slope of the graph

The substance density 

is the y-intercept negligible why or why not

Yes, because the y-intercept is 1.75% of y-max 

what would you predict would happen if you were to put one of the objects in water

It would float because the density is less than waters density. 

what would you expect to be the mass of a 45cm³ piece of the same substance

G = 0.9(45cm³) 

G= 40.5cm³
