Calculate the density of 2.00 cm^3 of salt having a mass of 4.32 g. Express the answer using proper significant figures and units.

Explanation:

Density = mass / volume

mass = 4.32 grams

volume = 2 cm^3

Density = 4.32 / 2

Density = 2.16 grams/cm^3

The units and the sig digs are correct for density.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
