Sulfur:

#### Explanation:

The mass percent of an element in a compound is basically this: Given any amount of a compound, what percentage of mass will that element take up?

We can find that using this formula:

Let's say the amount of penicillin G is

The mass of that would be:

If there's

That means that the mass of carbon is:

With this, we can find the mass percent of carbon in penicillin G.

We can use the same method to figure out the mass percents of the other elements in penicillin G:

- Hydrogen is
#(18xx1.008) / 334.384 = 0.0543 = 5.43%# . - Nitrogen is
#(2xx14.01) / 334.384 = 0.0838 = 8.38%# . - Oxygen is
#(4xx16.00) / 334.384 = 0.1914 = 19.14%# . - Sulfur is
#(1xx32.06) / 334.384 = 0.0959 = 9.59%# .

To confirm this, we can add these up; if our calculations were correct, they should add up to

Yay! :)
