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
