How many moles of co2 will be formed using 18 mol of co2?​

Answer:

2C₈H₁₈ + 25O₂ →16CO₂ + 18H₂O

Step-by-step explanation:

Calculate the moles of O₂ in 20 g.

moles (n) = mass (m)/molar mass (M)

m(O₂) = 20 g O₂

M(O₂) = 2 × 15.999 g/mol O = 31.998 g O₂/mol O₂

n(O₂) = 20 g/31.998 g/mol = 0.625 mol O₂

Use the mole ratio between O₂ and CO₂ in the balanced equation to calculate the moles of CO₂ that can be produced by 0.625 mol O₂.
