Answer:
<h2>1.48 moles</h2>
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>1.48 moles</h3>
Hope this helps you
For this question, we apply the Raoult's Law. The formula is written below:
P = P*x
where
P is the partial pressure
P* is the vapor pressure of the pure solvent
x is the mole fraction
The partial pressure is solved as follows:
P = Total P*x = (250 torr)(0.857) = 214.25 torr
Hence,
214.25 = (361 torr)(x)
<em>x = 0.593 or 59.3%</em>
