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 can you distinguish between NO2 and NO?
NO2 is a brown gas with a strong, unpleassant odor while NO is a colorless gas with a light, pleasant odor. NO2 is also toxic.
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 state of matter is NO2?

How many moles of bromine atoms in 1 mole of bromine gas Please show equation?
Bromine exists as a diatomic gas. Thus, there are two moles of bromine atoms in 1 mole of bromine gas.
How many moles of nitrogen gas are there in 35.7 gm of nitrogen gas?
molar weight of N = 14 grams/mole 35.7 grams/14 grams/mole = 2.55 moles
How many gas molecules are there in 1 mole of NO2?
The amount of 1 mole: 6.022 * 1023 (Avogadro's constant)
What sample at STP has the same number of molecules as 5 liters of NO2 at STP?
At STP, 1 mole of any ideal gas occupies 22.4 liters. Therefore, 5 liters of NO2 at STP will represent 0.22 moles (5/22.4), and this is the case for any other ideal gas. So, the answer is that 5 liter of ANY ideal gas will have the same number of molecules as 5 liters of NO2.
