How many ethene monomer molecules have to polymerise to form a polymer of molar mass 3000 g mol-1? 100408
Corrie writes .....
The molar mass of an ethene molecule, C2H4, is 28 g mol-1. Ethene molecules join up by addition (nothing lost) to form polyethene polymer. I'll leave you to do the necessary division to find the number of ethene molecules in a polymer with a molar mass of 3000 g mol-1!
Risk assessment
Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website.
For further guidance see our tutorial on Risk Assessment.
