At constant temperature, if the volume of the sample of gas increases to the given value, the pressure decreases to 0.92atm.
<h3>
Boyle's law</h3>
Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.
Boyle's law is expressed as;
P₁V₁ = P₂V₂
Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.
Given the data in the question question;
- Initial volume of the gas V₁ = 30.0mL = 0.03L
- Initial pressure of the gas P₁ = 1.53atm
- Final volume of the gas V₂ = 50.1mL = 0.0501L
- Final pressure of the gas P₂ = ?
We substitute our given values into the expression above to determine the new pressure.
P₁V₁ = P₂V₂
P₂ = P₁V₁ / V₂
P₂ = ( 1.53atm × 0.03L ) / 0.0501L
P₂ = 0.0459Latm / 0.0501L
P₂ = 0.92atm
Therefore, at constant temperature, if the volume of the sample of gas increases to the given value, the pressure decreases to 0.92atm.

Answer:
always repeats the same unit
made of smaller molecules
often made from repeating units
Explanation:
The chemical reaction equation will be as follows.
![H_{3}PO_{4} + 3NaOH \rightarrow Na_{3}PO_{4} + 3H_{2}O](https://tex.z-dn.net/?f=H_%7B3%7DPO_%7B4%7D%20%2B%203NaOH%20%5Crightarrow%20Na_%7B3%7DPO_%7B4%7D%20%2B%203H_%7B2%7DO)
In this reaction, 1 mole of
reacts with 3 mole NaOH. So, the number of moles of
present in 150 ml of 0.1 M solution is calculated as follows.
No. of moles =
= 0.015 mol
As it reacts with 3 moles of NaOH. Hence, no.. of moles of NaOH are:
![3 \times 0.015 mol](https://tex.z-dn.net/?f=3%20%5Ctimes%200.015%20mol)
= 0.045 mol
So, moles of NaOH in 400 of 0.2 M NaH is as follows.
No. of moles = ![\frac{400}{1000 \times 2}](https://tex.z-dn.net/?f=%5Cfrac%7B400%7D%7B1000%20%5Ctimes%202%7D)
= 0.080 mol
Hence, no. of moles remained after the reaction are as follows.
(0.080 - 0.045) mol
= 0.035 mol NaOH in 550 ml (400 ml + 150 ml)
As molarity is the no. of moles present in liter of solution. Hence, molarity of NaOH is as follows.
Molarity = ![\frac{\text{no. of moles}}{\text{volume in liter}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7Bno.%20of%20moles%7D%7D%7B%5Ctext%7Bvolume%20in%20liter%7D%7D)
=
= 0.0636 M
As,
= 0.0636 M. Hence, pOH will be 1.20.
As, pH + pOH = 14
pH = 14 - pOH
= 14 - 1.20
= 12.80
Also,
So,
=
M
Thus, we can conclude that pH of the given solution is 12.80 and its hydrogen ion concentration is
M.
