What mass of ni has as many atoms as there are n atoms in 63.0 g of no2?

Answer : The mass of Ni is, 80.346 g

Solution :

First we have to calculate the number of moles.

Now we have to calculate the number of atoms of

As 1 moles contains number of molecules

So, 1.369 moles contains number of molecules

One molecule has one nitrogen atom then number of molecules of will contain number of nitrogen atoms

As per question number of Ni atoms is equal to the number of nitrogen atoms

Number of Ni atoms= atoms

Number of moles =

Mass of Nickel =

Molecular mass of Nickel = 58.69 g/mol

Mass of nickel =
