help with limiting reagents and percent yield needed
the
reactions are the bromination of cis-stilbene and trans-stilbene.
The reagents and the moles of each reagent are in my data, as is
the moles of the products formed. The volume and mass of the
reagents are given as well. I need to know how to find the percent
yield and what the limiting reagents are for both the trans and cis
stilbene brominations. The information is there.

A compound with the molecular formula of C7H16 has the following physical properties: mp= -123.8 C; bp= 79.2 C; density = 0.6739 g/mL. There are several compounds with that formula. Use a reference book to determine the name and the structural formula of the isomer with those specific properties. Hint: Use the boiling point index at the end of the section “Physical Constants of Organic Compounds” in the CRC Handbook of Chemistry and Physics. Determine the boiling point, water solubility...
