Answer:
63.86 mg
Explanation:
Molar mass is the mass of 1 mol of compound / atom.
molar mass of the compound is - 310 g/mol
mass of 1 mol is - 310 g
therefore mass of 2.06 x 10⁻⁴ mol is - 310 g/mol x 2.06 x 10⁻⁴ mol = 0.06386 g
mass of calcium phosphate is - 63.86 mg
What are the options? I can try to give you an answer if options are provided.
2 KMnO4 (aq) + 5 H2O2 (aq) + 3 H2SO4 (aq) → 5 O2 (g) + 2 MnSO4 (aq) + K2SO4 (aq) + 8 H2O (l)
