How many molecules are in 1.75 moles of Caco3? 1.75 molecules
3.440 x 1023 molecules
1.054 x 1024 molecules
O 2.907 x 10-24 molecules

1.054 x 10²⁴ molecules

Explanation:

In order to convert moles of any given substance into a number of molecules, we need to use Avogadro's number, which states the number of molecules -or atoms, in the case of elements- present in one mol:

We now convert 1.75 moles into molecules:

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.
