Answer:
C. A larger area will usually contain more species than a smaller area.
Explanation:
Ans: Moles of CO2 = 0.25 moles
<u>Given:</u>
Mass of CO2 = 11 g
<u>To determine </u>
Moles of CO2
<u>Explanation:</u>
Moles = mass/molecular mass
Molecular mass of CO2 = 44 g/mol
Moles of CO2 = 11 g/44 g.mol-1 = 0.25 moles

Answer:
the number of neutrons in above isotope = A - Z = 27 - 13 = 14. Note: The molar mass of aluminium, which is average of atomic masses of all isotopes = 26.981538 g/mol, since 13Al27 is the major isotope.
