How do I balance chemical equations ?

Maru [420]

Answer & explanation:

To balance a chemical equation, we must make sure that there are equal amounts of each element in the equation on either side.

To balance an equation step-by-step we first start by counting the amount of each element on each side. If they aren't equal, we must make them amounts equal on either side.

After you make sure all the elements are balanced, the net charge on both sides must also be equal.

How many moles are in 123.0g (NH4)2SO4

Luda [366]

Here you go! There are 0.9307 moles in 123.0 g of the compound. I solved this by using a fence post method. I calculated the number of grams in one mol of (NH4)2 SO4 and got 132.16.

I did this by finding the atomic mass of each element on the periodic table (my work is in the color blue for this step)

After that, i divided the given mass by the mass of one mol of the compound.

The answer is 0.9307 moles!! I hope this helped you! :))
