Answer:
<h2>252.9 kPa</h2>
Explanation:
The new pressure can be found by using the formula

where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have

We have the final answer as
<h3>252.9 kPa</h3>
Hope this helps you
The correct answer is option 3. The degree of polarity of a chemical bond in a molecule of a compound can be predicted by determining the difference in the electronegativities of the atoms in a molecule of the compound. Electronegativities of the atom tell how the electrons are distributed in the molecule.
He improved and followed from the works of Luigi Galvani, which used a 'frog galvanoscope' as a prototype of measuring current. He recognized that a compass could actually measure current, given that it is placed near coil of wire.
Answer:
His results will be skewed because there was more water than stock solution. Which would cause the percentage solution to be less than 50% therefore the density would be less than the actual value.
Explanation:
The solution will have percentage less than that of 50%. Therefore the density would be less than the actual value.
Suppose there should be 50 mL of the solution, and he added 60 mL. So 10 mL of the solution is added more.
Suppose the mass of the solute is m.
Originally, the density is =

Now after adding extra 10 mL , the density becomes
.
Therefore, 
So the density decreases when we add more solution.
