What is the molarity of solution that contains 5.80 grams of nickel nitrate, ni (no3) 2 in 500. ml?

Molarity is defined as the number of moles of solute in 1 L of solution

molar mass of Ni (NO₃) ₂ - 182.7 g/mol

number of moles of Ni (NO₃) ₂ - 5.80 g / 182.7 g/mol = 0.0317 mol

number of moles in 500 mL - 0.0317 mol

therefore number of moles in 1000 mL - 0.0317 mol / 500 mL x 1000 mL/L

molarity of the solution is - 0.0634 M
