For each molecule of propane that is burned, there needs to be five molecules of oxygen present. Likewise, if there were a dozen molecules of propane, five dozen molecules of oxygen would be required. Similarly, for each mole of propane, five moles of oxygen are needed.

## How many moles of oxygen does it take to combust?

How many moles of oxygen are required to combust 84.6 mol of hydrogen? This shows that **42.3 moles** of oxygen are required to combust 84.6 moles of hydrogen.

## How many grams of oxygen are needed to completely react with the propane?

Answer: **120 grams** of oxygen are necessary to react completely with 33 grams of propane.

## How many moles of water will result from the complete combustion of 4 moles of propane?

Clearly, **four moles** of water result from each mole of propane.

## What is the mole equation?

Avogadro’s number is a very important relationship to remember: **1 mole = 6.022×1023 6.022 × 10 23 atoms**, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

## How many grams of oxygen gas will completely react with 3.8 moles of propane?

grams of Oxygen gas will completely react with 3.8 moles of Propane is **31.58**.

## How many grams of oxygen are needed to combust 20grams of propane?

Answer to Question #107196 in Chemistry for Mileini Valdez Ponsiano. How many grams of Oxygen are needed to combust 20 grams of propane? Answer: **72.6 g** of oxygen are needed to burn 20 g of propane.

## How many moles of O2 are needed to react with 8.4 moles H2S?

Answer to Question #112189 in General Chemistry for Tekeya Moss. How many moles of oxygen are needed to combine with 8.4 moles of H2S? Answer:**12,6mol**.

## What is the total number of moles of O2 that must react completely with 5.00 moles of c4h10?

Therefore, **5 moles** of C₄H₁₀ will **react** with = (**5** × 13)/2 = 33 **moles** of O₂. Thus, 33 **moles of oxygen**, O₂ is needed for the reaction.

## How many moles of water are produced from the reaction of oxygen with four moles of propane?

( 4 . 4 ) /1 = **16 moles** of water can be made.
