Answer:
<h3>The answer is 7.23 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>7.23 moles</h3>
Hope this helps you
Answer is: there is 0,592 moles of CF₂Cl₂.
m(CF₂Cl₂) = 71,66 g.
n(CF₂Cl₂) = m(CF₂Cl₂) ÷ M(CF₂Cl₂).
n(CF₂Cl₂) = 71,66 g ÷ 120,91 g/mol.
n(CF₂Cl₂) = 0,592 mol.
M - molar mass substance.
m - mass of substance.
n - amount of substance.
