#2.14"mol""/"l#

Well, we first need to convert #14.2g# of #"HCl"# in moles.

#"HCl"# has a molar mass of #36.46g"/"mol"#, so there is #(14.2g)/(36.46g"/""mol")=0.39# moles of hydrogen chloride in this case.

Molarity is expressed in moles per liter, so we need to convert #182mL# into liters.

#182mL=0.182L#

So, the molarity of the #"HCl"# will be #(0.39"mol")/(0.182l)=2.14"mol""/"l#
