1 mole of any substance is approximately 6.022*10^23 atoms (Avogadro's number)
So
(4.90*10^31 atoms) * (1 mole / 6.022*10^23 atoms) = 8.14*10^7 moles
C. -2 because it is higher up in the negatives whereas -6 and -13 are lower even though the number seems greater
Answer:
side length = 0.8 yards
area = side length^2= 0.8^2 = 0.64 or 64/100

Step-by-step explanation:
Answer:
y > 4
Step-by-step explanation:
2 (5y-4)>32
Divide each side by 2
2/2 (5y-4)>32/2
5y-4 > 16
Add 4 to each side
5y-4+4 > 16+4
5y > 20
Divide each side by 5
5y/5 > 20/5
y > 4
