Commercially available concentrated HCIcontains 38.0% HCl by mass (density = 1.19 g mL^(-1)). The molarity of the solution is

Answer»

10.40 M
5.70 M
12.38 M
13.46 M

Solution :38 g of HCl is present in 100 g of solution
Vol. of solution ` = (100)/(1.19)`
MOLARITY ` = ( (38)/(36.5) XX 1000)/( (100)/(1.19) ) = 12.28M `
