Answer:
Step-by-step explanation:
Use point (1, 3.5) on the graph
x = 1, y = 3.5
k = 3.5
There are 1.505535375e+24 atoms in 2.50 moles of iron.
I think it’s the second option
Answer:
224
Step-by-step explanation:
<u>Base:</u>
A = Bh
A = 8(8) = 64
<u>Sides:</u>
A = 1/2 Bh
A = 1/2 8(10)
A = 40
<u>Then you do 40(4) because there are 4 sides:</u>
40 (4) = 160
<u>Then you add up the base and the sides:</u>
160 + 64 = 224
(I think this is the right answer)
