25.9 grams fluorine (1 mole F/19.0 grams)(6.022 X 1023/1 mole F)
= 8.21 X 1023 atoms of fluorine
======================
There can be no conversion because -499°C is not an actual temperature. The lowest temperature possible for matter is absolute zero, which is -273.15°C or -459.7°F
That depends on what kind of octane you are referring to. n-octane has much different melting and boiling points than iso-octane. Octane has 18 structural isomers. Assuming the person asking the question is interested in either n-octane or iso-octane:n-octanemelting point: −57 °C, 216 K, -71 °Fboiling point: 125.52 °C, 399 K, 258 °Fiso-octane (also known as 2,2,4-Trimethylpentaneor isooctane)melting point: -107.38 °C, 166 K, -161 °Fboiling point: 99.3 °C, 372 K, 211 °F

Hydrogen is a colorless, odorless gas. It is the simplest element in nature, having one proton in the nucleus and one electron in the shell. Hydrogen is extremely light, and can be used to fill balloons. Hydrogen is HIGHLY flammable. When hydrogen burns, the result is water.

Remember K H D | d c m. Kilograms is three places to the left of grams. So you have to move the decimal place three times to the left. So in this case the answer is 0.259 kilograms.
259 mm = 25.9 cm which rounds to 26 cm
259 mL is about 8.757 US fluid ounces.
