Answer: The hydrogen ion concentration in molarity is 0.013
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pOH is calculated by taking negative logarithm of hydroxide ion concentration and pH is calculated by taking negative logarithm of hydrogen ion concentration
Putting in the values:
Now ,
The hydrogen ion concentration in molarity is 0.013
“About 300 kilometers across have irregular shapes because their internal gravity is not strong enough to compress the rock into a spherical shape” so I’m guessing it’s false ?
From,
RAM=element×its relative abudance/total abudance
=((107×13)+(12×109))/25
The answer is=107.96
It would be the same amount. So, 45 ml of NaOH is required to be added to the 45 ml of HCI to neutralize the acid fully. Here is a brief calculation:
Firstly, here is your formula: M(HCI) x V(HCI) = M(NaOh) x V(NaOH)
With the values put in: 0.35 x 45 = 0.35 x V(NaOH)
= 45 ml.
There is 45 ml of V(NaOH)
Let me know if you need anything else. :)

Answer:
P₂ = 0.87 atm
Explanation:
Given data:
Initial pressure = 1.10 atm
Initial volume = 19.2 L
Final volume = 24.3 L
Final pressure = ?
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
1.10 atm × 19.2 L = P₂ × 24.3 L
P₂ = 21.12 atm. L/ 24.3 L
P₂ = 0.87 atm
