Since you didn't give the actual volume (or any of the experimental values) I can only tell you how to do it. Do the calculation using the real (determined) volume of the flask. Then, re-do the calculation with v = 125ml. Take the two values and calculate % error; m = measured vol; g = guessed vol.
<span>[mW (m) - mW (g)]/mW (m) x 100% </span>
<span>(they want % error so, if it is negative, just get rid of the sign) </span>
graphite is a form of carbon in which carbon atoms are arranged in a layer.
Formula:
Given:
Density=3.4
Volume=500.0
Plug them into the formula:
Final answer: 1700g
H+O>h2o I believe this is the answer
