If you place 2.25 g of solid silicon in a 6.56-L flask that contains CH₃Cl with a pressure of 585 mm Hg at 25°C, what mass of dimethyldichlorosilane, (CH₃)₂SiCl₂, can be formed?

What pressure of (CH₃)₂SiCl₂(g) would you expect in this same flask at 95°C on completion of the reaction? (Dimethyldichlorosilane is one starting material used to make silicones, polymeric substances used as lubricants, antistick agents, and water-proofing caulk.)
