The takeoff distance required at sea level, standard temperature, and maximum takeoff. weight is between 5,500 and 6,000 feet. The landing distance required in dry conditions at sea. level, standard temperature, and maximum landing weight ranges from 3,000 to 3,500 feet.
To convert liters to grams, multiply the given number by 1000. A liter consists of 1000 milliliters and each milliliter is equal to 1 gram. Hence, 1 liter is equal to 1 kilogram or 1000 grams.
So divide by 10^9 to convert to moles, and multiply by 10 to convert to liters. If you know what the substance is, then you can multiply by the molecular weight (in grams per mole for example) to convert to grams, then convert to micrograms by dividing by 1000.
