What is the molarity of a solution made from dissolving 3.0 moles of KCl in 500 mL of Solution?

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

Reaction type : double replacement hcl + lioh = h2o + licl
