B is the correct answer i believe
Answer : The partial pressure of is 102.3 mmHg.
Explanation :
As per question,
Mass of = 62.9 g
Mass of = 33.2 g
Molar mass of = 18 g/mole
Molar mass of = 62 g/mole
First we have to calculate the moles of and .
Now we have to calculate the mole fraction of and .
Now we have to partial pressure of .
According to the Raoult's law,
where,
= partial pressure of water vapor
= total pressure of gas
= mole fraction of water vapor
Therefore, the partial pressure of is 102.3 mmHg.
The property of liquid that create meniscus in glass tubes is Adhesion
<h3>What is Adhesion?</h3>
Adhesion is the property of liquid in which two different or disimillar molecules or surfaces to cling to each other. For example, solids have a very high cohesive properties and this make them not to stick to the surfaces they come in contact.
Therefore, Adhesion property of liquids creates a meniscus in glass tube.
