## How many moles are of oxygen are required to react with hydrogen gas to produce 5 moles of water?

From this you can see that 5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water.

## How many moles of H2O are produced when 5 moles of oxygen are used?

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

## How many moles of H2O are produced when 2.5 moles of O2 react with H2?

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.

## How many moles of H2 are produced if 1 mole of O2 is produced?

1 Answer. One mole of H2 will produce one mole of H2O .

## How many moles of oxygen will you need for 100 grams of water?

Answer. There are 5.55 moles of water in 100g of it. There are 6.25 moles of oxygen in 100g of Water.

## What is the mass of 5 moles of hydrogen gas?

Answer: Hydrogen’s molar mass is 1.008 g/mol. Hydrogen gas’s formula is H2 meaning its composed of two hydrogens therefore its molar mass is 2.016 g/mol. 5 mol H2 x 2.016g/mol = 10.08 g.

## 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.

## What is the mole ratio of water to oxygen?

The mole ratio between oxygen and water is 1:2.

## How many grams of oxygen does it take to produce 9.60 moles of carbon dioxide?

Therefore, if we wanted to make 1g of carbon dioxide, we would need 32/44 g of oxygen and 12/44 g of carbon. Now, they’re asking how many grams of oxygen are needed to produce 9.6 grams of carbon dioxide, so that would be 9.6 · 32 / 44, which equals pretty close to 7 grams of oxygen (and 2.6 g of carbon).

## What is the mole ratio?

A mole ratio is a conversion factor that relates the amounts in moles of any two substances in a chemical reaction. The numbers in a conversion factor come from the coefficients of the balanced chemical equation.

## How many moles of O2 are in 4 moles of H2O?

This means that per four moles of oxygen, we get eight moles of water.

## How do I calculate moles?

- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.

## How many grams are in 1 mole of O2?

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

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

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.

## Is H2 one or two moles?

H2 – There are 2 moles of hydrogen atoms (1 mole of elemental hydrogen).
