## Introduction

In order to determine how many moles of O2 are produced when Ko is burned, we must first understand what Ko is and what it does. Ko is a solid element that, when burned, produces oxygen gas. When Ko is burned in oxygen, it breaks down into two molecules of oxygen gas. Therefore, when 0425 mol of Ko is burned, 8 moles of O2 are produced.

## What is a mole?

A mole is a unit of measurement used in chemistry to express the amount of a substance. One mole of a substance contains Avogadro’s number of atoms or molecules of that substance. For example, one mole of oxygen gas, O2, contains 6.022 x 1023 oxygen molecules.

## How many moles of oxygen are produced when 4.25 moles of potassium is burned?

When potassium is burned, it produces Oxygen gas. The equation for this chemical reaction is:

2K (s) + O2 (g) —> 2K2O (s)

So, for every 2 moles of potassium that are burned, 1 mole of oxygen gas is produced. Therefore, 4.25 moles of potassium will produce 2.125 moles of oxygen gas.

## What is the molar mass of oxygen?

The molar mass of oxygen is 16.0 grams per mole. Therefore, 16.0 grams of oxygen are produced when 0.425 moles of potassium is burned in oxygen.

## What is the molar mass of potassium?

The molar mass of potassium is 39.1 g/mol. Therefore, the mass of 0425 mol of potassium is 0425 x 39.1 g, or 167.775 grams.

## How many grams of oxygen are produced when 4.25 moles of potassium is burned?

According to the balanced equation for the combustion of potassium, 4.25 moles of potassium will produce 8.5 moles of oxygen gas. Therefore, 8.5 moles of oxygen gas will be produced when 4.25 moles of potassium is burned.

## How many liters of oxygen are produced when 4.25 moles of potassium is burned?

When potassium is burned, it reacts with oxygen to form potassium oxide. The chemical equation for this reaction is:

2K + O2 –> 2K2O

This means that for every mole of potassium that is burned, two moles of oxygen are produced. Therefore, 4.25 moles of oxygen are produced when 4.25 moles of potassium is burned.

## At standard temperature and pressure, how many moles of oxygen are produced when 4.25 moles of potassium is burned?

At standard temperature and pressure, 4.25 moles of potassium will produce 8.5 moles of oxygen.

## At standard temperature and pressure, how many grams of oxygen are produced when 4.25 moles of potassium is burned?

At standard temperature and pressure, 8.5 grams of oxygen are produced when 4.25 moles of potassium is burned.

## At standard temperature and pressure, how many liters of oxygen are produced when 4.25 moles of potassium is burned?

According to the chemical equation for the combustion of potassium, 4.25 moles of potassium will produce 8.5 moles of oxygen gas.

At standard temperature and pressure (STP), one mole of any gas occupies 22.4 liters. Therefore, 8.5 moles of oxygen gas would occupy 188 liters.
