Neither - its a measure of hydrogen ion concentration.
The element carbon, a pure compound or in water, does not have an associated pH level.
Polystyrene is definitely a compound. It is addition polymer compound. As a compound it is and alkene (ethene) with a phenyl group in place of one of the hydrogens. H2C = CH ){Phenyl) The alkene bond opens and polymerises (chaions up) with another alkene bond. -H2C-CH(Ph) -CH2- CH(Ph) -

Mixture
To calculate the grams of an element in a compound, you need to find the molar mass of the element and the compound. Then, use the formula: (mass of element/molar mass of compound) x molar mass of element. This will give you the grams of the element in the compound.
if it dissolves its a compound if not its an element.
NO = Nitrous Oxide - compound No = Nobelium - element
