Answer:
Vapour pressure of cyclohexane at 50°C is 490torr
Vapour pressure of benzene at 50°C is 90torr
Explanation:
Using Raoult's law, pressure of a solution is defined by the sum of the product sbetween mole fraction of both solvents and pressure of pure solvents.

In the first solution:


<em>(1)</em>
For the second equation:


<em>(2)</em>
Replacing (2) in (1):


-122.5torr = -0.250P°A

<em>Vapour pressure of cyclohexane at 50°C is 490torr</em>
And for benzene:


<em>Vapour pressure of benzene at 50°C is 90torr</em>
Answer:
Number of moles (n)=
molecular weight
weight
Weight=n×Molecular weight
=0.5×14

Selective serotonin reuptake inhibitors (SSRIs) are drugs that are antidepressants. These blocks the reuptake of a neurotransmitter leading to increases in their activity in the synaptic cells.
<h3>What are neurotransmitters?</h3>
Neurotransmitters are defined as the signaling molecules that are secreted by the nerve cells and act as signal transporter between the neurons and the other cells of the body.
The SSRIs class of drugs affects this neurotransmitter and blocks the pathway to the presynaptic cell. This, in turn, affects synaptic communication by increasing the amount of those SSRIs in the body and acting as a stimulant to treat various diseases.
Therefore, the SSRIs block the neurotransmitter and result in their effects.
