An ideal gas at STP occupies 22.4 liters. Calculating Oxygen as if it were an ideal gas there are . 893 moles of Oxygen in 20.0 liters.
Answer:
20 mol
Explanation:
First, balance the chemical reaction
C3H8 + 5O2 --> 4H2O + 3CO2
Using the mole ratio, we can multiply the moles of propane by 4 to find the moles of H2O.
5 × 4= 20
20 mol
64 divided by 4 is 16, so 16 km every 15 minutes.
15 x 3 is 45, so the distance is 16 x 3, and 16 x 3 equals 48.
It has traveled 48 km after traveling for 45 minutes. Hope this helped :)
