Answer:
Explanation:
You can convert the <em>density</em> into <em>atomic density</em> using the <em>atomic weight </em>and Avogadro's number
A dimensional analysis is very helpful:
Follow the chain: g cancels with g, mol cancels with mol; at the end, what remains is atoms/cm³, which is what you want.
Use that with your data:
To find density we have to know the values of density and mass. Here mass is given which i 180g.
we know the formula to find the density is:
Density = Mass / volume
so the density will be 180 / volume = 180g per unit volume
if we know the volume, we can find exact value of density.

We can see that 2 moles of The no react with 1 mole of O2 using this equation. 4.8 L NO x 1 L O2 / 2 L NO = 2.4 L of O2 are needed at constant pressure and temperature.
What is an example of pressure?
One can see a simple illustration of pressure by using a knife against a few fruit. If you press the flat side of the knife against the fruit, the top won't be cut. The force is spread more than a wide area (low pressure).
What are different types of pressure?
The physical pressure exerted to an object is referred to as pressure. Per unit area, a parallel force is applied to the surface of the objects. F/A (Force per Area) is the basic formula for pressure.
