Complete Question:
An iron atom has a mass of 9.27*(10)⁻²³ g and a cooking pot has a mass of 0.500 kg.
Use this information to answer the questions below:
1) What is the mass of 1 mole of iron atoms? Round your answer to 3 significant digits.
The mass of 1 mole of iron atoms is 55.8 g
Why?
The key to solve this question is the use of the Avogadro's Number (NA). This number tells us the amount of atoms found in 1 mole of a substance. So, to find the mass of 1 mole of iron atoms, we're actually finding the mass of 6.022 x 10²³ atoms.
The equation we are going to use to find the mass is shown below:
![mass_{1moleFe}=mass_{1atomFe}*NA=(9.27*10^{-23}g/atom)* (6.022*10^{23})\\\\mass_{1moleFe}=55.8 g](https://tex.z-dn.net/?f=mass_%7B1moleFe%7D%3Dmass_%7B1atomFe%7D%2ANA%3D%289.27%2A10%5E%7B-23%7Dg%2Fatom%29%2A%20%286.022%2A10%5E%7B23%7D%29%5C%5C%5C%5Cmass_%7B1moleFe%7D%3D55.8%20g)
2) How many moles of iron atoms have a mass equal to the mass of a cooking pot? Round your answer to 3 significant digits.
The moles of iron atoms that have a mass equal to the mass of a cooking pot is 8.96 moles
Why?
In this case, we are also going to use the mass of the cooking pot. We have to find first how many atoms are there in the cooking pot, and then we will find how many moles are represented by that mole of atoms:
Atoms in the cooking pot:
![\# atoms=0.500kg*\frac{1000g}{1kg}*\frac{1 atom}{9.27*10^{-23} } =5.39*10^{24}atoms](https://tex.z-dn.net/?f=%5C%23%20atoms%3D0.500kg%2A%5Cfrac%7B1000g%7D%7B1kg%7D%2A%5Cfrac%7B1%20atom%7D%7B9.27%2A10%5E%7B-23%7D%20%7D%20%3D5.39%2A10%5E%7B24%7Datoms)
Moles in the cooking pot:
![\# moles=5.39*10^{24}atoms*\frac{1 moles}{6.022*10^{23}atoms } =8.96 moles](https://tex.z-dn.net/?f=%5C%23%20moles%3D5.39%2A10%5E%7B24%7Datoms%2A%5Cfrac%7B1%20moles%7D%7B6.022%2A10%5E%7B23%7Datoms%20%7D%20%3D8.96%20moles)
Have a nice day!

Answer:
Since both H2 and H2O have the same ratio in the balanced equation, if you have 20 moles of H2 you will also get 20 moles of H20.
Hope this helps!
I would really appreciate if you mark me brainliest as I have been trying to get there for a veryyy long time now :)
Explanation:
Aromatic nitrogen bonded to hydrogen, as found in pyrrole must be represented as [nH] ; thus imidazole is written in SMILES notation as n1c[nH]cc1 . When aromatic atoms are singly bonded to each other, such as in biphenyl, a single bond must be shown explicitly: c1ccccc1-c2ccccc2 .
