How many atoms of copper will react with 33.9 l of nitrogen stp to produce copper nitride

Answer : The number of atoms of copper will be,

Solution :

As we know that 1 mole contains number of atoms

And,

At STP, 1 mole contains 22.4 liter volume of gas

First we have to calculate the moles of copper.

The balanced chemical reaction will be,

From the balanced chemical reaction we conclude that, 1 mole of nitrogen gas react with 6 moles of copper.

As, 22.4 L volume contains 6 moles of copper

So, 33.9 L volume contains moles of copper

Now we have to calculate the number of atoms of copper.

As, 1 mole of copper contains number of copper atoms

So, 9.08 moles of copper contains number of copper atoms

Therefore, the number of atoms of copper will be,

the answer is 303.15 or 303

i'm wiling to try and you : )
