It would be awesome if you can help me with this :)

Two station astronauts each need to perform three 8-hour EVAs during their 13-day mission to repair a damaged solar panel that was impacted by a micrometeoroid on the space station. How much oxygen will be needed to accomplish this? The units for this math problem are kilograms.
Each EMU has oxygen tanks (similar to scuba diving tanks) that work with a carbon dioxide removal system to allow a 6- to 8.5-hour spacewalk. Without the ability to remove carbon dioxide, the oxygen in the tanks would run out more quickly, because much would be tied up in exhaled gas. The amount of oxygen consumed, and carbon dioxide produced by a crewmember is dependent on his/her metabolic rate. (The life support system holds other things that get consumed during a spacewalk as well, including a battery and cooling water.) Each suit contains .54 kilograms of oxygen (at a pressure of 5,860.5kilopascals) for one EVA lasting between 6- and 8.5-hours.

Someone's cheating on their HAS assignment. X!!!

Really? Cheating on this is...well pathetic because it's very very basic...you need to reread the prompt and really look through it...the problem is very very very simple

Stupid Sean. You're an idiot

Yaaa some 1 is cheating in their hw...dats not fair... did u even try doing it??? Its very easy..HAS people do not give u stuffs dat we don't know.. try doing it urself

Maybe he has tried,and just needs to check to see if he did it correctly, it's not cheating, it is double checking.

To calculate the amount of oxygen needed for the EVAs, we first need to determine the total number of hours they will spend outside the space station.

Each astronaut needs to perform three 8-hour EVAs, so the total EVA time for one astronaut is 3 EVAs * 8 hours per EVA = 24 hours.

Since there are two astronauts, the total EVA time for both of them is 2 astronauts * 24 hours = 48 hours.

However, we also need to account for the fact that the spacewalks can last between 6 and 8.5 hours. To be conservative, let's assume the astronauts perform the maximum duration for each EVA, which is 8.5 hours.

Therefore, the total EVA time for both astronauts, considering the maximum duration of each EVA, is 2 astronauts * 3 EVAs * 8.5 hours per EVA = 51 hours.

Now, let's calculate the amount of oxygen consumed by each astronaut during one EVA. Each suit contains 0.54 kilograms of oxygen, which is equivalent to 540 grams (since there are 1000 grams in a kilogram).

To convert the oxygen mass from grams to moles, we need to divide the mass by the molar mass of oxygen. The molar mass of oxygen is approximately 32 grams per mole.

So, for one EVA, the amount of oxygen consumed by each astronaut is 540 grams / 32 grams per mole = 16.875 moles.

Finally, to calculate the total amount of oxygen needed for the EVAs, we multiply the moles of oxygen per EVA by the total number of EVAs:

Total moles of oxygen = 16.875 moles per EVA * 2 astronauts * 3 EVAs = 101.25 moles.

To convert moles of oxygen to kilograms, we multiply by the molar mass of oxygen (32 grams per mole) and divide by 1000 to get kilograms:

Total oxygen needed = 101.25 moles * 32 grams per mole / 1000 = 3.24 kilograms.

Therefore, to accomplish the three 8-hour EVAs, a total of 3.24 kilograms of oxygen will be needed.
