If 6 grams of a hydrocarbon gas have a volume of 4.8 cubic decimeter, what would be the
approximate molecular mass of this gas?
A 30 grams
B 40 grams
C 20 grams
D 48 grams

Label a-f based on the table using c for concentrated and d for dilute

If a molecule with a molecular formula of c13h18 is treated with an excess of h2 in the presence of finally divided pt metal under conditions required for maximum hydrogenation of the molecule to give a molecule with a formula c13h24, how many rings are in the molecule?

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
