Potassium sulfate number of atoms
WebHow many grams of sodium contain the same number of atoms as 10.0 g of potassium? What is the molar mass of magnesium sulfate? Calculate the number of moles of potassium ions in 16.2 g of potassium carbonate. (Enter the value to three significant figures without units.) Sodium sulfate combines with carbon to form sodium sulfide and carbon dioxide. WebCorrect option is A) ∵98 gH 2SO 4 contains 1 mole of H 2SO 4. 1 mole of H 2SO 4 contain =1 mole of sulphur atoms. ∴9.8 g of H 2SO 4 contain =0.1 mol of sulphur atom. Thus, number of sulphur-atoms =n×N A (in 9.8 g of H 2SO 4) =0.1×6.023×10 23=0.6023×10 23.
