The atmospheric pressure will be:
The pressure of the atmosphere resulting from the mercury column is 0.959 atm
What is atmospheric pressure?
The force that an object experiences from the weight of the air above it per unit area are known as atmospheric pressure.
Given: Height of mercury column = 729 mm Hg
To find: The pressure of the atmosphere
Calculation:
The atmospheric column resulting from the mercury column is calculated as follows:
1 atm =760 mm Hg
So, we can convert the 729 mm Hg to atm, and we get
Atmospheric pressure = 729 x 1 atm / 760 = 0.959 atm

Weight, the amount of force applied weight.
Answer:
0.0634 M HCl
Explanation:
Since HCl and NaOH react in a one-to-one mole ratio, we can just use M1V1 = M2V2 to solve for M1 (the concentration of HCl)
M1 = ? M HCl
V1 = 24.30 mL HCl
M2 = 0.120 M NaOH
V2 = 12.84 mL NaOH
M1(24.30 mL HCl) = (0.120 M NaOH)(12.84 mL NaOH)
M1 = 0.0634 M HCl
Answer:
a) 3.98 x 10^-10
Explanation:
Hello,
In this case, for the given pH, we can compute the concentration of hydronium by using the following formula:
Hence, solving for the concentration of hydronium:
Therefore, answer is a) 3.98 x 10^-10
