1. Sodium chloride (NaCl) commonly known as table salt, is the most common type of salt. What is the mass of 19.0 mol of sodium chloride (molar mass of sodium 22.99 g/mol and
chlorine 35.45 g/mol?

if they have a finite resultant

  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.
