Answer:
15.2 mL
Explanation:
First we calculate the volume of the copper
when this volume of copper is added to the water, the water level will rise by the level of the volume of copper. So the final volume is:
14.6 mL + 0.5580 mL = 15.158 mL
Since the measuring cylinder is graduated to one decimal place , we can round this up to 15.2 mL
When publishing experimental results, it is always advisable to have your peer review those results. This peer can confirm the results that you got and thus they will be more reliable.
Also, you will be sure that what what you are publishing is correctly presented as it is always good to have a fresh eya to double-check what is written.
N = m/M
Where,
n = number of moles
m = mass of substance
M = molar mass of substance
0.8286 = m / 30.067
Multiply both sides by 30.067
m = 24.9135162g
I think it is a white dwarf star
