When 2.5 moles of oxygen gas (o2) are consumed in their reaction, mol of carbon dioxide are produced?

The reaction is not given here but we take an example reaction to understand how to calculate moles.

Let the balanced equation for the reaction is
C3H8 (g) + 5 O2 (g) → 3CO2 (g) + 4 H2O (g)

From here 5 moles of oxygen produces 3 moles of carbon dioxide

So 2.5 moles of oxygen produces 2.5/5 x 3 = 0.5 x 3 = 1.5 moles of carbon dioxide

l dont know l am s sorry

i'm pretty sure it is letter c.) car
