Calculate the average mass in grams of 1 atom of oxygen.
June. Children, I'll be going over structure six. Question number six, which talks about a more public So in me you know of molecules of a compound means the muller must those.
The molar mass of an element just referring to an element We're not talking about compounds or molecules or anything. The molar mass of an element is simply the mass of one mole of the atoms of that element.
Hello. So for this question is going to be using the I do class a question which is P vehicles NRT. So it's gonna be PV Okay, over our team Since we were looking for 21% we're going to do Finally end. It cost 21 percent of PV over artie. Okay, so let's do the substation. So there's still point 21 Times The pressure, 1.01 10.5 The volume is one should be committed. The uh, They are is a constant. Right? That's 8.314 times the temperature. Just 25°.. They need to convert that to Kelvin. That's going to give us to my age. So the number of moles looking for us. It went 5, 2 more. Yeah. All right. So now I want to couple the math. We also know that m as we go to math over the mullah Mas between the MAs is going to be a number of most during the mamas the molecular weight of oxygen, the royal couple of oxygen molecule. It's 32 g per mole. Okay, So the mass is going to be yeah. Uh, sorry, 8.52 times 32. Okay. You know, I get 273 grabs. This is going to be final answer for the mass of accident. 273 grounds. Thank you very much.
Hello. So this question really is indeed. I do this equation which is uh the vehicles. Nrt that pressure that are volume. A number of most the email address, constant temperature in kelvin. We just isolate in We're gonna get this oxygen is 21 So we're gonna be using 21% in our formula. Uh huh. We were given were given everything in the question. So we just do a substitution. So this is the percentage converted to fraction uh no pressure or volume are as a constant temperature. It's 25° and it's converted coven. You're going to get that mm. Not that the number of moses also equal to the mass of the molar mass. So if you isolate em you got this the molecular weight of oxygen. It's 32 grand piano. So we put it back in and get Uh huh. 273g. Okay, thank you very much.
