Explanation:
Gamma rays are most similar!
it will be in group 16 of the periodic table and they are called chalcogens
and it's categorize as Nonmetals
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
n(O₂)=1.407 mol
M(C₃H₈)=44.1 g/mol
m(C₃H₈)/M(C₃H₈)=n(O₂)/5
m(C₃H₈)=M(C₃H₈)n(O₂)/5
m(C₃H₈)=44.1*1.407/5=12.410 g
the mass of propane is 12.410 g
