Question

Part A:How many moles of barium ions are there in 6.29 molmol Ba(NO3)2Ba(NO3)2?

Part B:How many moles of nitrate ions are there in 6.29 molmol Ba(NO3)2Ba(NO3)2?

Part C:How many moles of nitrogen atoms are there in 6.29 molmol Ba(NO3)2Ba(NO3)2?

Part D:How many moles of oxygen atoms are there in 6.29 molmol Ba(NO3)2Ba(NO3)2?

Answer 1

Ba(NO3)2 having one Ba⁺² ion and 2 NO₃^- ions.

Part A: No. of moles Barium (Ba⁺²) ions: 6.29 mol

Part B: No. of moles of NO₃^- ions: 2 x 6.29 mol = 12.58 mol

Each Ba(NO3)2 have 2 Nitrogen atoms.

Part C: No. of Nitrogen atoms present: 2 x 6.29 mol = 12.58 mol Nitrogens

Each Ba(NO3)2 have 6 oxygen atoms.

Part D: No. of moles of oxygen atoms: 6 x 6.29 mol = 37.74 mol Oxygen atoms
