To find moles from any number of atoms, always divide by the constant called Avogadro's Number. This number is representative of the number of atoms or molecules in a mole of any substance and is equal to about

.
So, for this problem, we take the number of atoms of oxygen and divide by Avogadro's Number.
Answer: 0.661 moles (after rounding)

Answer:
≈ 395,8 J/(kg * °C)
Explanation:
m = 44 g = 0,044 kg
= 22 °C
= 33,6 °C
Q = 202 J
The formula is: Q = c * m * (
)
c =
Calculating:
c = 202 J / 0,044 kg * (33,6 °C - 22 °C) ≈ 395,8 J/(kg * °C)
