Vedclass · Answer

(C) The density of liquid $HCl$ is $1.17 \ g/cc$. This means $1 \ cc$ of $HCl$ has a mass of $1.17 \ g$. Therefore,$1000 \ cc$ $(1 \ L)$ of $HCl$ has a mass of $1170 \ g$. The molar mass of $HCl$ is $1.008 + 35.45 = 36.458 \ g/mol$,which is approximately $36.5 \ g/mol$. Molarity = $\frac{	ext{mass of solute in grams}}{	ext{molar mass} 	imes 	ext{volume of solution in litres}}$. Molarity = $\frac{1170 \ g}{36.5 \ g/mol 	imes 1 \ L} = 32.05 \ mol/L$.

The molarity of liquid $HCl$ with a density equal to $1.17 \ g/cc$ is: (in $M$)
