There are actually three acceptable answers to the previous questionbecause there are three unique locations in a hexane molecule to replace a ¹2C with a ¹3C. Ifyou have not already done so, draw the other two acceptable answers to the previous question.The peak at m/z = 87 is called the [M+1]* peak. Construct an explanation for this name.Use your periodic table to calculate the weight, in grams, of 1 mole of hexane to foursignificant figures (XX.XX).Explain why 1 mole of hexane weighs slightly more than 86 grams.

Since you have asked a multiple sub-part question, we will solve first 3 sub-parts for you. For…
