A gasoline tanker must deliver gas to a station only assessable via bridge. The bridge has been damaged and can only hold 10.0 tons of weight at a time (1 ton = 2000 pounds).  If the truck itself weighs 6.50×103 pounds, how many gallons of gas (density = 0.700 g/mL) can the truck safety carry to the station?
