Question

The acid secreted by the cells of the stomach lining is a hydrochloric acid solution that contains 0.00774 mol of HCL pee 0.0500L of solution.What is the concentration of the solution 

Answer 1

Given

Moles of HCl=0.00774mol

Volume of HCl Solution=0.0500L

Concentration of the solution =??

Calculating the concentration of the HCl solution:

$Concentration of HCl Solution =\frac{moles of HCl(mol)}{volume of solution(L)}$

$=\frac{0.00774mol}{0.0500L}$

=0.155mol/L or 0.155M

The concentration of the solution is 0.155 M.
