In those exercises you need to determine the structure of the unknown product.

 

Based on the precision, molecule modification as well as the observed monoisotopic mass you should be able using chemcalc to find a small list of possible molecular formula.

 

From the MF you can calculate the degree of unsaturation and then use the mass fragmentation and the IR to get some idea of possible molecules.

 

Finally you may use the NMR spectrum to remove any ambiguity and draw the structure of the unknown.

 

For the NMR spectrum you are able to define the zone that should be integrated by pressing the 'ALT' key and then one click 'from' and one click 'to'. The relative integration will be displayed under the annotation.

 

Based on the molecular formula you can determine the amount of protons there are at the level of each signal.

 

In CDCl3, water is around 1.5ppm and CHCl3 at 7.27.

In DMSO-d6, water is at around 3.5 and DMSO-d5 at 2.5..
