Admita uma solução aquosa saturada de HCL com concentração percentual mássica de 36,5% e densidade igual a 1g/mL. Calcule a concentração molar dessa solução, expressa em mol/L

Molar concentration of the solution = 10.0 mol/L

Explanation:

English Translation

Admit a saturated aqueous solution of HCL with a mass percentage concentration of 36.5% and density equal to 1g / mL. Calculate the molar concentration of this solution, expressed in mol / L

Solution

Mass concentration of the solution = 1 g/no

Percentage concentration of the solution that is HCl = 36.5%

Mass concentration of HCl

= 36.5% × 1g/mL = 0.365 g/mL

(Concentration in mol/L) = (Concentration in g/L) ÷ (Molar Mass)

Concentration of HCl in g/L = 365 g/L

Molar Mass of HCl = 36.46 g/mol

Concentration of HCl in mol/L = 365 ÷ 36.46 = 10.011 mol/L = 10.0 mol/L

Hope this Helps!!!

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
