Final answer:
The molarity of hydrochloric acid in the solution is approximately 7.34 M.
Step-by-step explanation:
The molarity of hydrochloric acid in a solution can be calculated using the formula:
M = (n/HCl) / V
where M is the molarity, n is the number of moles of HCl, and V is the volume of the solution in liters.
First, we need to calculate the number of moles of HCl using the given mass of HCl and its molar mass:
n = mass / molar mass = 79.1 g / 36.5 g/mol = 2.167 mol
Next, we convert the volume of the solution from milliliters to liters:
V = 295 mL / 1000 mL/L = 0.295 L
Finally, we can plug in the values into the formula:
M = (2.167 mol) / (0.295 L) ≈ 7.34 M
