Question

How many moles of IO2 contain 5.12×1027 molecules of IO2?

Answer 1

Answer: 8502.2 mol IO₂

Step-by-step explanation:

This is a unit conversion problem, and we will be converting molecules of IO₂ to moles IO₂ using Avogadro's constant (6.022 x 10²³ molecs/1 mol).

I wrote it two different ways in case the fraction can be a bit difficult to read. :)

5.12 x 10²⁷ molecs IO₂ (
`(1 mol IO_(2) )/(6.022*10^(23) molecs IO_(2) )`) = 8502.2 mol IO₂

5.12 x 10²⁷ molecs IO₂ (1 mol IO₂/6.022 x 10²³ molecs IO₂) = 8502.2 mol IO₂

I hope this helps! :)
