Question

The number of oxygen atom in 46g of NO2 is approximately​

Answer 1

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 2

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 $12.046*10^{23}$
