How many moles are in a sample of 4.57 x 1024 atoms of neon (Ne)? 7.59 mol Ne
27.5 mol Ne
91.4 mol Ne
151 mol Ne

Can someone please explain how you divide 4.57 x 10^24 by 6.022 x 10^23?? Thank you

‘which reaction would most likely require the use of an inert electrode?

At a certain temperature the rate of this reaction is first order in hi with a rate constant of : 0.0632s2hig=h2g+i2g suppose a vessel contains hi at a concentration of 1.28m . calculate how long it takes for the concentration of hi to decrease to 17.0% of its initial value. you may assume no other reaction is important. round your answer to 2 significant digits.
