How many atoms are contained in the chemical formula #2AgNO_3#?

Answer 1

In one silver nitrate formula unit, there are 3 oxygen ATOMS, 1 nitrogen ATOM, and 1 silver atom.

It is evident that there are two silver atoms, two nitrogen atoms, and six oxygen atoms in two formula units of silver nitrate.

We can improve this answer by using the mole concept. The mole is simply a VERY large number: #N_A= 6.022xx10^23#.

If we have 2 moles of silver nitrate, there are #N_A# silver atoms, #2xxN_A# nitrogen atoms, and #6xxN_A# oxygen atoms. Using the molar masses of each element, we can therefore predict the MASS of a mole of silver nitrate as #169.87# #g*mol^-1#, where this mass is the sum of the individual molar masses of the constituent elements.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
