Question
I am having a really hard time with this post lab. Here is my dataI had 10 mL of t-pentyl alcohol and I need to convert it to grams.
I also had 25 mL of HCL and need to convert it to miles
Data and Calculations. Repor the folowing and show al nedesany calculations, Reterur notebook table of reagents for all necessary physical constants. The mass (g) of t-pentyl alcohol you used. 9.1u ail groms a) Imo I mol 98.29 2-mevnst-2 b) Moles of t-pentyl alcohol (1 pt): outaro ( )(w) mous wt used c) The moles of HClI added (concentrated hydrochloric acid is 12.1 M HCI) (1 pt): 3043 mous as mi of HCL HCL =(25 mL)(1-189) (incl =0-8843 mous HCL 1 Mous 1 nc( 36.ASg d) Theoretical yield of t-pentyl chloride (mol) (1 pt):
Explanation / Answer
1) Density of t-pentyl alcohol = 0.811g/ml
mass of t-pentyl alcohol = 10ml × 0.811g/ml = 8.11g
Molar mass of t-pentyl alcohol = 88.148g/mol
No of mole of t-pentyl alcohol = 8.11g/88.148g/mol = 0.09200
2) No of moles of HCl added = (12.1mol/1000ml)×25ml =0.3025
3) 1:1 mole reaction
t-pentyl alcohol is limiting reagent
0.09200 mole of t-pentyl alcohol should give 0.09200 mole of t-pentyl chloride
Molar mass of t-Pentyl chloride =106.592g/mol
Theoretical yield = 0.09200mol ×106.592g/mol =9.806g
