What is the formula mass of ammonium carbonate (#(NH_4)_2CO_3#)?

Answer 1

Take the atomic masses from the Periodic Table, and add them up.

I'll give you a start: #(NH_4)_2CO_3#. There are 2 nitrogen atoms, whose formula mass is 14 g, and 8 hydrogen atoms whose formula mass is 1:

Twox14 plus eightx1 =?

The formula mass of ammonium carbonate ((NH₄)₂CO₃) is calculated by summing the atomic masses of all the atoms in the formula:

((N x 2) + (H x 8) + (C x 1) + (O x 3)) = ((14 x 2) + (1 x 8) + (12 x 1) + (16 x 3)) = (28 + 8 + 12 + 48) = 96 g/mol

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.
