Note: You are calculating mass which is determine the gram(g)
You will have to cancel out the mol
(28.97 g/mol) * mol will give grams by itself
Given the mass 3.33 moles of air
28.97 g/mol * 3.33 mol = 96.47 grams
Solution: 96.5 grams

Does sodium satisfy the ostet rule?
Charra [1.4K]

Answer:

The rule is especially applicable to carbon, nitrogen, oxygen, and the halogens, but also to metals such as sodium or magnesium. ... All four of these electrons are counted in both the carbon octet and the oxygen octet, so that both atoms are considered to obey the octet rule.

Can someone please help me with this!!!<br><br> ( I chose to stop using water bottles )

Answer:

Flushing goldfish down the toliet

Explanation:

This would help the planet because goldfish are a very evasive species that has been harming our natural enviroments lakes and rivers. Ever since people have been flushing them down the toliet including me since I've had over six they have been finding their ways into our ecosytem and damaging nature. You may think that goldfish are a cute and small pet species to keep in a fish tank but the fish can grow in the right conditons up to 16.1 inches long and can top over five pounds in the wild. Unfortunately most goldfish never thrive like this in fish tanks due to nasty inadequate housing and feeding conditions. And most do not live up to their expected life span in the wild of 15 to even thirty years due to their living conditons. Did you know, goldfish will actually jump out of their tank in a final desperate search for better living conditions and enviroment to live in to meet their physiological needs. But lets get back to the problem so don't be to quick to feel sorry for them, when people flush them down the toliet they repopulate somehow in our lakes and rivers. Even through, it is not clear how they got there, which the suspected culprit is the sewer system. They threaten the natural enviroment tho because they are obnivores and they eat a mixtures of plants and animal specimen. You are probrably thinking why is this a problem, well its because goldfish are particullary greedy eaters and will eat, eat, and feast on the natural envrioment they infestated. And the waste they leave on the enviroment will promote the growth of algae which could cause an extent of enviromental damage. Of course goldfish are not impacted by this algae growth for adaptation reasons which shield them. This is not the main problem tho the main problem of this is that female goldfish can produce up to 1000 eggs at a time. And to make things worse unlike other fish species where the parents of the eggs leave the eggs for predaetors and well the elements of nature the goldfish instead guard their nest foriciously from predaetors that eat fish eggs in which effectively shields the populations young from danger. And to just add to the chaos the goldfish sadly have no real natural predaetor in the unitedstates which just causes more problems since they have no one killing them. And did I mention that they could live up to a real possibility of thirty years. And that they are forocious eaters that could eat a variety of types of foods. All of these facts in the end lead to two things first stop flushing your pet goldfish down the toliet and secondly now you know how golfish impact our planet.

Give brainliest please it took me over thirty minutes of thinking!

A sample of gas in a 14.6 L flexible container is at 25.0oC and 1.00atm. What is the volume of the sample when heated to 220.0oC
inn [45]

Answer: 24.1 L

Explanation:

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1\text{ and }T_1 are the initial volume and temperature of the gas.

V_2\text{ and }T_2 are the final volume and temperature of the gas.

We are given:

V_1=14.6L\\T_1=25.0^oC=(25+273)K=298K\\V_2=?\\T_2=220.0^0C=(220+273)K=493K

Putting values in above equation, we get:

\frac{14.6}{298K}=\frac{V_2}{493}\\\\V_2=24.1L

Thus the volume of the sample when heated to 220.0oC and the pressure is constant is 24.1 L
