Fredrick Banting was the original inventor of insulin
Insulin was actually discovered by Nicolae Paulescu, a Romanian scientist in 1916. His work predated that of Fredrick Banting by five years, although Banting went on the win the Nobel Prize along with John Mcleod, although Charles Best was not recognized for the contributions to their re-discovery of insulin. The common misconception that insulin was "invented" by Canadians persists to this day. Also, insulin is a naturally occurring substance and thus was discovered. However, different means by which it can by synthesized have been invented.
To find the molar mass of insulin, you first need to calculate the number of moles of insulin in the sample using the Avogadro's number and the number of molecules. Then, divide the grams of insulin by the number of moles to find the molar mass. The molar mass is expressed in grams per mole.
Insulin was never 'invented', simply purified and synthesized. Importance? That's hard to summarize in just a paragraph. Try reading about Frederick Banting and you'll understand what it did for the world.
The chemical formula of insulin is C256H381N65O79S6
The first water purifier was invented by Peter Spitz in 1975. He developed a carbon filter system that could remove impurities and provide clean drinking water.

There where many inventions in the 1920s as it was a time of change but 2 big ones are the car and insulin. I also think that crayobs were invented in the 1920s.
It is not really known who invented the first notebook. This is because it was invented a very long time ago.
Insulin was isolated in 1922 by Frederick Banting...
he invented insulin doy! :D
