The molarity of 5.80 g of LiNO₃ in 505 mL of solution is 0.167 mol/L

Given mass of solute LiNO₃ = 5.80 g

Volume of solution = 505 mL = 0.505 L

Molar mass of LiNO₃ = 68.946 g/mol

Therefore, Number of moles in 5.80 g LiNO₃ = 5.80 / 68.946 = 0.0841 mol

Hence, Molarity of the solution = Number of moles of solute / Volume of the solution

= 0.0841 / 0.505 = 0.167 mol/L
