How many moles of carbon dioxide will form if 2.5 moles of c3h8 is burned

7.5 mol  

Step-by-step explanation:

Step 1. Balanced equation

C₃H₈ + 5O₂ ⟶ 3CO₂ + 4H₂O

Step 2. Calculation:

You want to convert moles of C₃H₈ to moles of CO₂

The molar ratio is 3 mol CO₂:1 mol C₃H₈

Moles of CO₂ = 2.5 mol C₃H₈ × (3 mol CO₂/1 mol C₃H₈)

                      = 7.5 mol CO₂

The reaction will form 7.5 mol of CO₂.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire
