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

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.
