Exactly 299,792,458 meters per second (m/s). I say exactly because at one point the official length of a meter was modified slightly to make c come out to a even number of meters per second, rather than having some annoying decimal places.\n\nStill, most people prefer to round up to 300,000,000 m/s.

This is using VP=VP, Boyle's Law of Gases.  By the way, mm Hg is the same thing as torr.  \n400 mL * 500 mm Hg = V * 760 torr\nV=263.2 mL, so your answer checks.  You may want to check your significant figures, though.

It's 1,000,000,000 (1 billion) times larger.\n\n1 m = 1000 mm - "cubic" means volume, or 3 dimensions, so you multiply 1000 x 1000 x 1000.
