Answer:
3.29 M
Explanation:
Molarity refers to the molar concentration of a solution and it can be calculated using the formula below:
Molarity (M) = number of moles (n) ÷ volume (V)
According to this question, the mass of HCl was given to be 60.4 grams and the volume of water as 505 mL.
Using mole = mass/molar mass to convert mass of HCl to moles
Molar mass of HCl = 1.0079 + 35.453 = 36.4609g/mol
mole = 60.4g ÷ 36.4609g/mol
mole = 1.66mol
Volume of water = 505mL = 505/1000 = 0.505L
Molarity, M = 1.66 ÷ 0.505
Molarity of HCl solution = 3.29 M
