A 100g of sample of a compound is combusted in excess oxygen and the products are 2.492g of CO2 and 0.6495 of H2O. Determine the empirical formula of the compound?

The empirical formula : C₁₁O₁₄O₃

The assumption of the compound consists of C, H, and O

mass of C in CO₂ =

mass of H in H₂O =

mass of O :

mass sample-(mass C + mass H)

mol of  C :

mol of H :

mol of O :

divide by 0.0155(the lowest ratio)

C : H : O ⇒

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
