A commercially sold conc. $HCl$ is $35 % HCl$ by mass. If the density of this commercial acid is $1.46 g / mL$ , the molarity of this solution is : (Atomic mass : $Cl = 35.5 amu, H = 1 amu$ )

Options:

Answer:

Solution:

Molarity $M = \frac{x \times d \times 10}{m_{B}}$

$= \frac{35 \times 1.46 \times 10}{36.5} = 14 M$

$m_{B} =$ molecular mass of solute

$d =$ density of the solution in $g / L$

$x = %$ solute by mass.
