Solution Preview
These can be tough questions, but we have quite a bit of information here. The percentages do not specify, but I will assume they are percent by mass. What we do is take the molar mass of 2015 amu (we can figure out the finer detail of that later) and multiply the percentages to find masses of each of the elements listed.
eg. For Carbon 0.4287 x 2015 amu = 864 amu
Hydrogen.......................... = ...
