Answer:
Molarity of solution = 0.727M
Explanation:
Molarity of solution is defined as moles solute per Liter of solution. For the posted problem use M = n/V where n = moles of solute and V = Liters of solution. That is ...
n = 58.9g/180.16g·mole⁻¹ = 0.327 mole (3 sig. figs.)
V = 450.0ml/1000ml·L⁻¹ = 0.450L (3 sig. figs.)
∴ Molarity = n/V = 0.327mole/0.450L = 0.727mol/L = 0.727M

<u>Answer:</u> The volume of concentrated hydrochloric acid required is 16.53 mL
<u>Explanation:</u>
To calculate the volume of concentrated solution, we use the equation:
where,
are the molarity and volume of the concentrated solution
are the molarity and volume of diluted solution
We are given:
Conversion factor: 1 L = 1000 mL
Putting values in above equation, we get:
Hence, the volume of concentrated hydrochloric acid required is 16.53 mL
