Answer:

Molar mass of nitrogen dioxide(NO2) is equal to 46g/mole. Molar mass of nitric oxide(NO) is equal to 30g/mole. 92 g of nitrogen dioxide means 2 moles of nitrogen dioxide. Since each atom of nitrogen dioxide contains 2 atoms of oxygen, 2 moles of nitrogen dioxide will contain 4 moles of oxygen.

Answer:

Number of oxygen atoms present in 46g of nitrogen dioxide is equal to 12×10²³atoms.

Explanation:

Given: mass of nitrogen dioxide =46g

The molecular mass of NO₂ = 14+32 =46g

We know that one mole of any compound contains 6.023×10²³ of molecules.

So, 46g of nitrogen dioxide contains = 6.023*10^{23} molecules of  NO₂

One molecule of  NO₂ contains =2 atoms of oxygen

6.023*10^{23} molecules of  NO₂ contain =2*6.023*10^{23}

                                                               =12.046*10^{23} atoms of oxygen

Therefore number of oxygen atoms will be equal to 12.046*10^{23}
