How many moles of oxygen (O) atoms are in a sample of 3.98 × 1023 atoms? 0.661 mol O 1.51 mol O 6.60 × 1022 mol O 2.40 × 1047 mo
lidiya [134]
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 6.022* 10^{23} &#10;.

So, for this problem, we take the number of atoms of oxygen and divide by Avogadro's Number. 

\frac{3.98*  10^{23}  O_{2} atoms  }{6.022*  10^{23} atoms/mol  } = 0.6609 moles

Answer: 0.661 moles (after rounding)

Make sense?

What is the specific heat of a 44 g piece of metal if 202 Joules of heat are required to
Ray Of Light [21]

Answer:

≈ 395,8 J/(kg * °C)

Explanation:

m = 44 g = 0,044 kg

t_{1} = 22 °C

t_{2} = 33,6 °C

Q = 202 J

The formula is: Q = c * m * (t_{2} - t_{1})

c = \frac{Q}{m * (t_{2} - t_{1} )}

Calculating:

c = 202 J / 0,044 kg * (33,6 °C - 22 °C) ≈ 395,8 J/(kg * °C)
