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.
Hydrogen melts at a temperature of -259.16 degrees Celsius. When hydrogen is heated above this melting point, the kinetic energy of the molecules increases, causing them to overcome the forces holding them together in a solid state, and transition into a liquid state.
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

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.
