The correct answer is H=5
141.3/3.14/3²=5
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
Answer:
C = 5/9 (F - 32)
This is a temperature scale change comparison.
By this we understand, that ,
1°C = 5/9°F
Which is equal to, 5/9°F = 1°C
These two statements are satisfied by I. and II.
So, the correct answers are, I. and II.
