# How many moles of water are made from the reaction of 2 2 moles of oxygen?

Contents

Explanation: The equation says that for every 1O2 , there are 2H2O produced. Therefore, if you have 2.2O2 , you must have 2.2⋅2H2O , or 4.4 moles of H2O .

## How many moles of water are produced when 2 mol of oxygen reacts with hydrogen?

We can just as easily read this chemical equation as “two moles of hydrogen react with one mole of oxygen to make two moles of water.” All balanced chemical reactions are balanced in terms of moles.

## How many moles of water are produced when 2 moles of NH4 react with excess oxygen gas?

see we have two moles of NH4, so we replace 4 NH4 by 2 NH4. thus, 2 moles of NH4 react with 3 moles of oxygen gas to produce 2 moles of NO2 and 4 moles of H2O.

## How many moles of water are produced in this reaction?

ANSWER: 0.490 moles of water, H2O are produced in this reaction.

## How many moles of water are in 4 moles of oxygen?

Assuming that oxygen is our limiting reactant (because it is not otherwise specified), we can find that per one mole of oxygen, we get two moles of water. This means that per four moles of oxygen, we get eight moles of water.

## How many grams of water are in 2.5 moles?

According to reaction below, when one mol of oxygen reacts with two mol of hydrogen, two mol of water is produced. Thus, when 2.5 mol of oxygen reacted with hydrogen, 2 * 2.5 mol = 5 mol of water is produced. The molar mass of water is 18 g/mol. One mol of water weighs 18 g.

## What is the formula for calculating moles?

Chemical Reactions and Masses of Reactants and Products

1. mass O2 = moles(O2) × molar mass(O2) (a) Calculate moles Mg = mass(Mg) ÷ molar mass(Mg) moles(Mg) = m ÷ 24.31. …
2. mass MgO = moles(MgO) × molar mass(MgO) (a) Calculate moles Mg = mass(Mg) ÷ molar mass(Mg) moles(Mg) = m ÷ 24.31.

## How many moles of oxygen are in N2O5?

Percent composition by element

Element Symbol # of Atoms
Nitrogen N 2
Oxygen O 5

## How many moles of oxygen are present in 2 moles of hno3?

Explanation: In 2 moles of nitric acid there are 2 moles of hydrogen atoms, 6 moles of oxygen atoms, and 2 moles of nitrogen atoms. Since the molar mass of nitrogen (atomic nitrogen!) is 14.01⋅g , we simply double the number. From where did I get the molar mass?

## How many moles of O2 can be produced from 12 moles KClO3?

How many moles of O2 can be produced by letting 12.00 moles of KClO3 react? The KClO3 / O2 molar ratio is 2/3. 2 mol KClO3 / 3 mol. O2 = 12.00 mol KClO3 / x = 18.00 mol.

## How many moles of H2O are formed?

Since all compounds in this reaction have 1 mole, it will not affect the number of moles (n). If 1 mole of HCl or NaOH gives you 1 mole of H2O , then the number of moles in H2O is: [ 1÷1×1 ] = 1 mole.

## What is the first step in most stoichiometry problems?

the first step in any stoichiometric problem is to always ensure that the chemical reaction you are dealing with is balanced, clarity of the concept of a ‘mole’ and the relationship between ‘amount (grams)’ and ‘moles’.

## How many moles are in 50 g of water?

1 Answer. There are 3 moles of O in 50 g.

## How many moles of oxygen are required?

3 moles of oxygen gas are required.

## How many moles of water are produced from 5 moles of oxygen?

One mole of this, plus five moles of O2 gives me three moles of CO2 and four moles of H2O.

## How many moles of O2 are in H2O?

A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
