A sample of dangerously reactive fluorine gas is contained in a stainless steel container which has a 31 L capacity at a pressure of 160 pounds per square inch and a temperature of 26.0◦C. What mass of fluorine gas sample is in the stainless steel container? 1. 10.3098 g 2. 522.362 g 3. 6.87318 g 4. 27.4927 g 5. 18.3285 g

The mass of fluorine gas sample  in the stainless steel container is

522.455 grams

Explanation:

To solve the question, we note the given parameters to see if we have enough facts to provide an answer

Volume of container = 31 L = 0.031 m³

Pressure of the fluorine in the container = 160 psi

Temperature of the fluorine gas in the container = 26 °C

We have the universal gas equation given by

P·V = n·R·T

Where P = Pressure 160 psi = ‪1103161‬ Pa

V = Volume = 31 L = 0.031 m³

n = Number of moles

T = Temperature = 26 °C = (273.15 + 26) K= 299.15 K and

R = Universal gas constant = 8.314 J/mol·K

Therefore n = = = 13.75 moles of fluorine

The molar mass of fluorine gas = 37.99681 g/mol

Therefore the mass of fluorine gas contained in the stainless steel container is 13.75 moles × 37.99681 g/mol = 522.455 grams

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
