What is the number of moles of chemical units represented by 9.03x10^24?

15 moles

Explanation:

According to Avogadro’s number 1 mole of a substance has 6.023 x 1023 particles.  

Particles could be atoms, molecules, ions, formula unit etc. Avogadro’s number allows scientists to manipulate very large number as real life material contain very large numbers of particles such as atoms, molecules, ions etc.  

9.03 x 10²⁴ x 1 mole/ = 15 moles

have a great day because if you dont you and i will be sad

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
