# Which of the following is not represented by 1 mole of nitrogen gas?

Contents

The correct option to the following question is (iii), which is 6.023 × 10²³ Nitrogen atoms. One mole is defined as the amount of substance that contains as many elementary particles as present in 12 grams (0.012 kg) of the carbon-12 isotope. One mole of nitrogen gas you have 6.023×10²³ molecules of nitrogen gas, N2.

## Which of the following does not represent one mole?

Which of the following does NOT represent a mole? For variants A and B the masses are equal Molar mass of the compounds. For variant C 6.02 x 10^23 is the Avogadro’s number, therefore the three variants represent 1 mole. So, 16 grams of oxygen do not represent a mole.

## What is the mole of 1 mole of nitrogen atom?

1 mole of nitrogen atoms is equivalent to the gram atomic mass of nitrogen. Therefore, 1 mole of nitrogen atoms contains 14 g.

IT IS SURPRISING:  What is a mole simple explanation?

## What is one mole of nitrogen gas?

The mass of one mole (molar mass) of nitrogen gas (N2) is 28.0 g/mol .

## What is the mass of 1 mole of nitrogen gas?

Mass of one mole of nitrogen atoms is 14 g.

## Which of the following represent 1 mole?

Therefore, the answer is 4g of Helium contains one mole of the substance.

## Which of the following represent 1 mole of dioxygen gas at STP?

(a, d) 1 mole of dioxygen represents 32 g of O2, 22.7 L of O2 or 6.022 x 1023 molecules of O2 gas.

## How many atoms are in 1 mole of nitrogen?

How many atoms are in 1 mole of nitrogen? 6.02 x 10 23 atoms!

## How many moles of nitrogen atoms are combined?

moles of nitrogen atoms, or 3.44 moles of nitrogen atoms.

## How many particles are in 1 mole of nitrogen?

In order to have one mole of things, let’s say particles, you need to have 6.022⋅1023 particles → this is known as Avogadro’s constant and acts as the definition of the mole. So, in one mole of nitrogen gas you have 6.022⋅1023 molecules of nitrogen gas, N2 .

## How many moles are in 1 gram of nitrogen gas N2?

You can thus say that a mole of nitrogen gas is equivalent to 2 gram-atoms of nitrogen, or that 1 gram-atom of nitrogen gas is equivalent to 12 moles of nitrogen gas.

## How many grams are in 1 mole of No?

Once you know that, you can use Avogadro’s number as a conversion factor to help you determine how many molecules would be present in that many moles. So, nitric oxide has a molar mass of 30.01 g mol−1 , which means that one mole of nitric oxide has a mass of 30.01 g .

## What is the mass of 1 mole?

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

## What is the mass of 1 nitrogen atom?

Therefore, we have calculated the mass of one atom of nitrogen as 2.32×10−23g.

## What is the mass of 4 moles of nitrogen atoms?

Mass of 1 mole of nitrogen atoms = 14 g. 4 moles of aluminium atoms. Mass of 1 mole of aluminium atoms = 27 g. Mass of 4 moles of aluminium atoms = (27 x 4) = 108 g.
