Agas at constant pressure occupies 0.400 l at 50.0°c. what volume will it have at 300.°c? if you could show work that would really be appreciated.

This can be solved using the Combined Gas Law. The formula for that is

Let's go ahead and fill in our known values. Since pressure remains the same, it doesn't matter what number we use, so let's assume 1 atm on both sides. For temperature, remember to convert it to Kelvin first (K = C + 273).

Go ahead and simplify both sides.

0.001238 =  

Multiply both sides by 573.

0.7095 = x L

So, at 300° C, your gas will occupy 0.7095 L.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
