This problem is providing the initial volume and pressure of nitrogen in a piston-cylinder system and asks for the final pressure it will have when the volume increases. At the end, the answer turns out to be 2.90 atm.
<h3>Boyle's law</h3>
In chemistry, gas laws are used so as to understand the volume-pressure-temperature-moles behavior in ideal gases and relate different pairs of variables.
In this case, we focus on the Boyle's law as an inversely proportional relationship between both pressure and volume at constant both temperature and moles:
Thus, we solve for the final pressure by dividing both sides by V2:
Hence, we plug in both the initial pressure and volume and final volume in order to calculate the final pressure:

We can solve this problem when we use the conditions of a gas at standard temperature and pressure. It has been established that at STP where the temperature is 0 degrees Celsius and the pressure is 101.325 kPa, the volume of 1 mole of gas is 22.4 L. We will use this data for the calculations.
68.5 L ( 1 mol O2 / 22.4 L O2 ) = 3.06 mol O2
Answer:
(1) It shows arrangement of elements based on modern periodic law.
(2) There are 18 vertical columns known as groups.
(3) There are 7 horizontal rows known as periods.
Answer:
35g/l
Explanation:
Salinity is practically the saltiness of the water, in basic terms. It's basically the amount of salt dissolved in water. Ocean water has a salinity of around 35g/l (that's about 3.5% of which is dissolved salt in water!). However, Atlantic Ocean (the ocean with the saltiest water), can range up to 37g/l.

The molar solubility of AgCl:
The molar solubility of AgCl in a 0.050 M NaCl solution is 8 x 
M 
What is solubility?
The solubility is the quantity of reagent required to saturate the solution or bring about the dissociation reaction's equilibrium.
Reaction:
The dissociation reaction of AgCl in water is:
⇄ 
Each mole of AgCl that dissolves in this reaction yields 1 mole of both and 
. The concentration of either the Ag or Cl ions would then be equal to the solubility.
Solubility= [] = []
Calculation:
in 0.050 M NaCl, the [] = 1 x 
ksp = [] x []
1.6 x 
= [
] x ( 5 x )
[] = 5 x 
x 1.6 x
[] = 5 x 1.6 x 
[] = 8 x M
