        Q: The hydrocarbon used in the manufacture of foam plastics is called styrene. Analysis of styrene indicates the?
A: 1 g of styrene contains 0.9225 g C and 0.0775 g H , thereby 104 g of styrene would contain :   C : 104 * 0.9225 g / twelve g/mol = 7.995 mol  H : 104 * 0.0775 g / 1 g/mol = 8.06 mol   Round these to the closest entire number :   C : 8 mol  H : 8 mol   Therefore 1 mole of styrene contains 8 moles of C and 8 moles of H.  Therefore the molecular formula is C₈H₈ ( that 's `` C8H8 '' in case the subscripts do n't display properly ) . 

Q: The empirical formula of styrene is CH; the molar mass of styrene is 104.14 g/mol. How many H atom?
A: C10H20O maybe it is one option .
