Answer:
Explanation:
Pair A:
Answer:
nitrogen
Moles of oxygen:
Number of moles = mass/ molar mass
Number of moles = 2.50 g/ 32 g/mol
Number of moles = 0.08 mol
Moles of nitrogen:
Number of moles = mass/ molar mass
Number of moles = 2.50 g/ 28 g/mol
Number of moles = 0.09 mol
Pair B:
Answer:
nitrogen
Moles of nitrogen:
Number of moles = mass/ molar mass
Number of moles = 21.50 g/ 28 g/mol
Number of moles = 0.77 mol
Moles of carbon dioxide:
Number of moles = mass/ molar mass
Number of moles = 15.2 g/ 44 g/mol
Number of moles = 0.341 mol
Pair C:
Answer:
Both have same number of moles.
Moles of oxygen:
Number of moles = mass/ molar mass
Number of moles = 0.054 g/ 32 g/mol
Number of moles = 0.002 mol
Moles of carbon dioxide:
Number of moles = mass/ molar mass
Number of moles = 0.081 g/ 44 g/mol
Number of moles = 0.002 mol
