Commercial concentrated HCl is 37%, which you may assume means weight percent. It density is 1.18 g/mL. Find

a) the molarity of the HCl

b) the volume of solution containing 0.100 mol of HCl

c) the mass of solution containing 0.100 mol of HCl

 

-----------------------------------------

 

a) 11.9748 M

( 설명 http://ywpop.tistory.com/5301 )

 

b) 0.100 mol / (11.9748 mol/L)

= 0.008351 L

= 8.351 mL

 

c) 8.351 mL * (1.18 g/mL)

= 9.854 g
