gas
The average velocity of the atoms in a monatomic gas can be calculated using the formula ( v_{rms} = \sqrt{ \frac{3kT}{m} } ), where ( k ) is the Boltzmann constant, ( T ) is the temperature in Kelvin, and ( m ) is the molar mass of the gas. For neon, the molar mass is approximately 20.18 g/mol. Plugging in the values, we find that the average velocity is about 516 m/s.
5...The volume of 4.0 cubic meters of gas is kept under constant pressure. Its temperature is increased from a minus 73 degrees Celsius to 127 degrees Celsius. What is the new volume of the gas? 8 cubic meters...
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams per mole. Therefore, a 6.94 mole sample of sodium hydroxide would contain approximately 278 grams (6.94 moles x 40 grams/mole).
About 278 grams.

278 feet = 84.73 meters.
To determine how many times A goes into 278, we need to know the value of A. If A is a specific number, you can divide 278 by that number to find the quotient, which represents how many times A fits into 278. For example, if A is 5, then 278 divided by 5 equals 55.6, meaning A goes into 278 a total of 55 times with a remainder.
278 cm is equal to ~109.45 inches.
