4Na + O2 - 2Na2O
Moles= 4:1 ratio
3.82 x 4 = 15.28 moles
Answer:
atoms
Explanation:
Given that,
Given mass = 13200 g
Molar mass of potassium = 39.0983 g/mol
Let there are n number of moles. It is equal to mass divided by molar mass. It is equal to :
Let there are x atoms in 13200 g of potassium (k). It can be calculated :
So, there are atoms.
I would say that there is 270 grams left. since its F2 you have three things there.
divide 405 by 3
you will get 135.
but there are 2 F's so multiply that by 2 and you will get 270.
the final answer should be 270 grams left.
