Question

How many atoms of nickel can be found in a 1.00 g sample? somone help pleaseeeeeeeeeeeeeeeeeeeeeeeeeeewith a cherry on top c:

Answer 1

use n=m/MW ..moles equals mass divided by molecular weight

n= (1g)/(58.69g/mol) =

since 1 mole = 6.023x10^23 atoms (avogadros number)

multiply the amount of moles you have by avogadros number and voila

Answer 2

okay whatttttttttttttt? I dont understand the question at all...or your answer please help! <3

Answer 3

do you know what a mole is?

Answer 4

so you have 1 g of nickel right? a formula you should know is n=m/MW, which is moles equals mass divided by molecular weight (or more accurately, mass).

using that formula you can find the number of moles, then to find the number of ATOMS, you multiple however many moles you have by avogadros number (6.023x^23).

Answer 5

do you understand

Answer 6

we just learned this in class today , the teacher is mean -.-.....I kinda understand but I'm pretty sure I'mma get this wrong anyway. Thanks though!! :)

Answer 7

you go to school on sunday? lol

well know what a mole is a proportion like saying a dozen.

1 dozen of atoms = 12 atoms
1 mole of atoms = 6.023x10^23 atoms

use n=m/MW and it's basically plug and chug

Answer 8

Its monday here in florida , lol. where are YOU from ? hmmm , I'm gonna try what you say , brb. :D

Answer 9

LOL oh yeah, I'm in canada and it's thanksgiving. do it, let me know what you get to make sure its correct !

Answer 10

14.56......I'm not sure If I did this right :/

Answer 11

lol... Happy thanksgiving!

Answer 12

thanks! haha okay so you divided (1g)/(58.69g/mol)= 0.017 moles right?

now you multiply 0.017 x (6.023x^10^23)
(make sure you know how to input \[6.023x10^{23}\] into your calc)

you should get 1.026 x 10^22

Answer 13

wth , I don't understand this at all ...this is my worst subject ... THANKS SO MUCH THOUGH! why arent you celebrating thanksgiving? lol

Answer 14

lol what don't you understand? haha il try to explain

i already did, had turkey n stuffing and pumpkin pie. now i'm working on a lab, due to trmw but i'm stuck :S

Answer 15

stuck on what ? and I'm okay, you've helped enough! :) and yummy... I had cereal for lunch -.- lol

Answer 16

what grade are you in ?

Answer 17

stuck on the interpretation of nitro- nitrite- isomers on the infrared spectrum.. haha I'm in uni 2nd year.

Answer 18

cereal does not cut it haha

Answer 19

lol....I'm in like 10th grade

Answer 20

haha enjoy school while it's easy
