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

Chemistry
1 answer:
Luda [366]3 years ago
7 0
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! :))
