C	156.4	20.0ml
D	170.9	21.0ml

1-) Find Mass Intercept: ?

2-) Find Slope: ?

3- )Slope Calculation: ?

4-) what is Equation for your line:?

5-) What is the physical property of the system that corresponds to the graphical value of m (slope)?

6-) What is the physical property of the system that corresponds to the graphical value of b (intercept) ?

7-) Graphical Density Graph:

Answer 1

1. Mass intercept is -13, Line crossing at y axis
2. Slope = 8.75 is the ratio of AB/BC
3. Slope = AB/BC = (105-80)/(15-11) = 35/4 =8.75
4. y=mx+b        m is slope which is equal to 8.75 and b is intercept which is equal to -13 y= 8.75x+(-13) or y= 8.75x-13
5. Slope is AB/BC which is nothing but mass/volume called as density, the density of the sample will be 8.75 g/ml.
6. Intercept is negative which is wrong, either in calculation or in measurement.
