Calculate the ph of a solution obtained by mixing 100ml each of 0.1M HCL, 0.1M HNO3 and 0.1M NaOH solutions.
Volgvan
Given:

Volume of each of the solutions = 100 mL of each
Concentration of HCl = 0.10 M
Concentration of HNO3 = 0.10 M
Concentration of NaOH = 0.10 M

If all are mixed in one solution, the pH will surely be low since there are two acids mixed with one base. The pH range should be 1 - 5. <span />

If a balloon contains 3.00 L of air that has a pressure of 36.74 psi, what is the gas volume (the volume of the balloon) once it
Troyanec [42]

Answer:

7.5 L

Explanation:

At constant temperature and number of moles, Using Boyle's law  

{P_1}\times {V_1}={P_2}\times {V_2}

Given ,  

V₁ = 3.00 L  

V₂ = ?

P₁ = 36.74 psi = 2.5 atm (Conversion factor, 1 psi = 0.068046 atm)

P₂ = 1 atm  (Atmospheric pressure as it comes to surface)

Using above equation as:

{P_1}\times {V_1}={P_2}\times {V_2}

{2.5\ atm}\times {3.00\ L}={1\ atm}\times {V_2}

{V_2}=\frac{{2.5}\times {3.00}}{1}\ L

{V_2}=7.5\ L
