## How many moles of O2 are required for the complete combustion of butane?

Each mole of butane needs 6.5 moles of oxygen, so **13 moles** of oxygen is required for 2 moles of butane in a complete combustion.

## What volume of oxygen is required for the complete combustion of propane?

**100 litres** is the volume of oxygen needed at ${{27}^{o}}C$ and 760 mm of Hg pressure for combustion of propane.

## How many moles of O2 are needed?

This equation tells us that for every 2 moles of NO2 formed ; we require **1 mole of O2** .

## 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 are needed to burn the butane completely?

Hence, **312 grams** of oxygen is essentially required for complete combustion of 3 moles of butane gas.

## How much oxygen is required for the complete combustion of 128g of methane?

Thus, **16 g of oxygen** are required for burning 4 g of methane.

## What volume of oxygen is required for complete combustion of 2.2 gm of propane at NTP?

The volume of oxygen gas required is **5.58 L**.

## What volume of O2 is required for complete combustion of 1.4 Litres of propane?

Answer: 1L of propane required **5L** of Oxygen gas.

## What volume of oxygen is measured at 0 C and 1 atm?

Hence volume of oxygen gas measured at 0oC and 1atm, ineeded to burn completely 1L of propane gas (C3H8) under the same conditions is **5L**.
