The graph shows the relationship between mass and volume for pure silver. Use the graph to determine the density of pure silver
Natalija [7]

Answer:

C. Slope and 10.49 g/cm^3

Step-by-step explanation:

We're missing the graph itself, but I can make an educated guess:

- Assuming x = volume and y = mass:

p = \frac{m}{v}

density = mass/volume

x = volume = run

y = mass = rise

mass/volume = rise/run = slope

The slope of the line (assuming the graph is purely linear) represents mass/volume, which is the formula for density.

I had to Google the density of silver itself. Do the math from the graph for a more appropriate answer, as the graph may be less scientifically precise.

Is there a rational number between 1/7 and 1/8
telo118 [61]
1/7 = 2/14 =  <span> <span> <span> 0.1428571429 </span> </span> </span>
1/8 = 2/16 =  0.125
2/15 = <span> <span> <span> 0.1333333333 </span> </span> </span>
So, 2/15 is between 1/7 and 1/8
(and there are an infinite amount of numbers between 1/7 and 1/8)
