pH

=

7.6

then

pOH

=

14

−

pH

=

The mass percentage of hydrochloric acid within a solution is 15.00%. given that the density of this solution is 1.075 g/ml, fin

Morgarella [4.7K]

Given the mass percentage of HCl solution = 15.00 %

This means that 15.00 g HCl is present in 100 g solution

Moles of HCl = $15.00 gHCl*\frac{1 mol HCl}{36.46 g HCl} =0.411molHCl$

Density of the solution = 1.075 g/mL

Calculating the volume of solution from density and mass:

$100 g *\frac{1mL}{1.075 g} =93.0 mL$

Converting volume from mL to L:

$93.0 mL * \frac{1 L}{1000 mL} =0.093 L$

Calculating the molarity of HCl solution from moles and volume:

$\frac{0.411 mol}{0.093 L} =4.42 mol/L$
