Commercially available concentrated hydrochloric acid conatins 38% HCl by mass.
What is the molarity of this solution if the density is 1.19 g `cm^(-3)`?

Text Solution

Verified by Experts

`"Volume"="mass"/("density")=100/(1.19)=84.03cm^(3)`
Number of moles of HCl
`=38/(36.5)=1.04` moles
Therefore, molarity = `1.04/(84.03)xx1000=12.38`
