# Which contains the greatest number of moles of oxygen atoms?

Contents

formic acid, HCO2H, contains the greatest number of moles of oxygen atoms.

## Which compound has the greatest number of oxygen atoms?

So we can see that H2SO4 has the greatest percent oxygen by mass, so if we had an equal mass of each compound, the mass of oxygen in H2SO4 would be the greatest, meaning that it has the greatest number of oxygen atoms.

## Which contains the greatest number of moles of oxygen atoms IB chemistry?

46 g of ethanol contains 1 × 6.023 × 1023 number of oxygen atoms. 2. 1 mol of formic acid. 46 g of HCOOH contains 2 × 6.023 × 1023 number of oxygen atoms.

## Which contains the greatest number of moles of oxygen atoms 1 mole of ethanol?

1 mol water has 1 oxygen atom that is 1 mol oxygen atom. Therefore, formic acid has maximum moles of oxygen (2). 1 mol ethanol has 1 oxygen atom that is 1 mol oxygen atom.

## Which of the following contains largest number of atoms?

4 g of hydrogen contains the largest number of atoms.

• (A) 4 g of hydrogen (molar mass 2) corresponds to 2 moles of molecules or 4N number of atoms where N is the Avogadro’s number (6. …
• (B) 16 g of oxygen (molar mass 32) corresponds to 0.5 moles of molecules or N number of atoms where N is the Avogadro’s number (6.

## How do you find moles of oxygen atoms?

So, guys, in one mole of oxygen, how many grams are there if you take a look at the product table? Or maybe you remember the atomic weight of oxygen. It is 16 g per one mole, right, so 16 g per one more. So all you have to do is divide 35.2 by 16 and that will give you the answer in moles to to moles of oxygen atoms.

## How do you find the greatest number of moles?

Determining Number of Moles of a Compound With Known Mass

To find the number of moles in a sample, simply weigh it and divide the weight by the molecular weight. The quotient is equal to the number of moles.

## Which of the following has the greatest No of oxygen atoms 10 moles of water?

Explanation: The answer of this question is: b; 200 gram of C12 h22 o11.

## How many moles of ethane is required?

Answer: Ethane on combustion gives CO2 and H2O as follows. =0.5 x 30=15 gm Ethane. 0.5 mole or 15 gm Ethane is required to produce 44 gm.

## How many moles are in H2O?

The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.

IT\'S FUNNING:  What is meant by a mole in terms of number of particles?

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

This means that in 1 mol of ethanol, there are 46 g, thus the term molecular mass and molar mass are often used interchangeably.

## Which of the following contains largest number of moles?

As we can see that, water has the highest value for the number of moles in respect to other compounds. So, the largest number of molecules are present in water.
