Answer:
2.58 gramos de argón
Explanation:
D=m/v
D: Densidad, m:masa ,v:volumen
1.45=m/1.78
1.45*1.78=2.581
Just multiple 19.3 by 15 because cm^3 will cancel outand you are left with g with represents mass
<span>They don't use opinion based research.

Answer:
secondary alcohol
Explanation:
NaOH in solution provides OH- nucleophile.
When 2-chloropropane is treated with NaOH, nucleophillic substitution reaction takes place.Here leaving group is Chlorine atom (Cl).
Here OH- replaces Chlorine (Cl) to form 2-propanol which is a secondary alcohol.(OH group attached to 2° carbon)
Other possibility is elimination reaction in which NaOH acts as base.
NaOH acts as base when it is concentrated and aqueous NaOH acts as nucleophile.
In that case,the product formed will be an alkene.(not there in option)
