Hey there!
2.70 moles of Fe x (6.022 x 10^23) atoms of Fe = 1.63 x 10^24 atoms of Fe
_______________________
1 mole of Fe
Answer: 1.63 x 10^24 atoms of Fe
Hope this helps :)
Answer:
C
Explanation:
because it remains the same
Answer:
Any device that contains electronic parts
1.75 moles of Solute or 1.75n.
To find this, you'll need to use the molarity equation which is M = 
List the given items to organize better:
M (Molarity) = .35
V (Volume) = 5L [must always be in Liters]
n (Moles) = ?
Now, for the equation, substitute the variables with the given numbers:
.35 = 
Isolate the variable by multiplying the volume, 5, onto both sides. This will give you the answer of:
1.75 = n
