Answer:
0.20 mol Br2O and 0.20 mol HBrO have the same number of oxygen atoms
Explanation:
0.20 mol Ba(OH)2 and 0.20 mol H2SO4
In Ba(OH)2 there are 2 moles of O atoms in every mol of Ba(OH)2.
Number of O atoms in 0.20 moles Ba(OH)2 = 2*0.20 = 0.40 moles O atom
In H2SO4 there are 4 moles of O atoms for every mol of H2SO4.
Number of O atoms in 0.20 moles H2SO4 = 4*0.20 = 0.80 moles O atom
⇒ 0.20 mol Ba(OH)2 and 0.20 mol H2SO4 do not have the same number of oxygen atoms.
0.20 mol Br2O and 0.20 mol HBrO
In Br2O there is 1 mol of O atoms in every mol Br2O
Number of O atoms in 0.20 moles Br2O = 0.20*1 = 0.20 moles O atom
In HBrO there is 1 mol of O atom in every mol HBrO
Number of O atoms in 0.20 moles HBrO = 0.20 *1 = 0.20 moles O atom
⇒ in 0.20 moles Br2O and 0.20 moles HBrO we have the same number of oxygen atoms
0.20 moles of Oygen contains: = 0.20 * 6.022*10^23 = 1.2 *10^23 O atoms
0.10 mol Fe2O3 and 0.50 mol BaO
In Fe2O3 there are 3 moles of O atoms in every mol of Fe2O3
Number of O atoms in 0.10 moles Fe2O3 = 0.10 * 3 = 0.30 moles O atom
In BaO there is 1 mol of O atoms in every mol BaO
Number of O atoms in 0.50 mol BaO = 1*0.50 = 0.50 moles O atom
⇒ 0.10 mol Fe2O3 and 0.50 mol BaO do not have the same number of oxygen atoms.
0.10 mol Na2O and 0.10 mol Na2SO4
In Na2O there is 1 mol of O atoms in every mol of Na2O
Number of O atoms in 0.10 mol Na2O = 1*0.10 = 0.10 moles O atom
In Na2sO4 there are 4 moles of O atoms in every mol of Na2SO4
Number of O atoms in 0.10 mol Na2SO4 = 4*0.10 = 0.40 moles O atom
⇒ 0.10 mol Na2O and 0.10 mol Na2SO4 do not have the same number of oxygen atoms.
