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
Yes it solidifies into ice at very low temperatures below about 150 K and low pressures.
Well, isn't that a happy little question. Hydrogen melts at a very low temperature, around -259 degrees Celsius. When you gently warm it up, the hydrogen molecules start moving more freely and eventually transition from a solid to a liquid state, just like magic. Just remember to be patient and gentle with it, and you'll see the beauty of hydrogen melting before your eyes.
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

259 metres = 850 feet
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.
