N has 7 protons
O has 8 protons (O2 therefore 16)
So 1 molecule of NO2 gas has 7 + 16 = 23 protons
1 mole of NO2 gas (6.022 * 1023 molecules) have 138.506 * 1023 protons.

How many atoms of sodium are in 0.250 moles of Na2SO4?
in 0.25 moles there are 1.505*10^23 molecules (1 mole of any element=6.023*10^23 molecules)
What does NO2 stand for?
NO2 stands for nitrogen dioxide, which is a reddish-brown gas that is a common air pollutant.
Is NO2 a base?
NO2 is not a base. It is a nitrogen dioxide molecule which can act as an acidic gas when dissolved in water, forming nitric acid.
What state of matter is NO2?
It is commonly found as a gas.
How can you distinguish between NO2 and NO?
NO2 is a brown gas with a pungent odor and is a stronger oxidizing agent compared to NO, which is colorless and odorless. You can use chemical tests or analytical instruments like gas chromatography or infrared spectroscopy to differentiate between the two gases based on their unique properties.
How many gas molecules are there in 1 mole of NO2?
There are approximately 6.022 x 10^23 gas molecules in 1 mole of NO2. This number is known as Avogadro's constant.
What sample at STP has the same number of molecules as 5 liters of NO2 at STP?
5 liters of NO2 at STP contains Avogadro's number of molecules (6.022 x 10^23). Therefore, any sample with the same number of molecules as 5 liters of NO2 at STP would also contain Avogadro's number of molecules.
How many gas particles are one mole of gas?
There would be 6.022 x 1023 gas paricles in one mole of that gas.
What is the name of the brown gas called?
The brown gas is called nitrogen dioxide (NO2). It is a reddish-brown gas that is a common air pollutant produced by combustion processes.
How can you distinguish between NO2 and NO?
NO2 is a brown gas with a pungent odor and is a stronger oxidizing agent compared to NO, which is colorless and odorless. You can use chemical tests or analytical instruments like gas chromatography or infrared spectroscopy to differentiate between the two gases based on their unique properties.
How many atoms of sodium are in 0.250 moles of Na2SO4?
in 0.25 moles there are 1.505*10^23 molecules (1 mole of any element=6.023*10^23 molecules)
What is the density in grams per liter of ammonia gas at STP?
The density of ammonia gas at STP (Standard Temperature and Pressure) is approximately 0.771 grams per liter.
How many oxygen atoms does 1 mole of 02 gas have?
1 mole of O2 gas contains 2 oxygen atoms because each molecule of O2 consists of two oxygen atoms bonded together.
Which gas is more aboundant in environment?
no2
Which is the laughing gas?
Nitrous oxide, NO2
What is the volume of 12g of NO2 at STP?
At STP, 1 mole of an ideal gas occupies 22.4 liters. 0.335 mol x 22.4 L = 7.50 L .................. 1 mol
Does a noble gas have twice as many electrons as protons?
equal numbers of protons and electrons
