The concentration of species in 500 mL of a 2.104 M solution of sodium sulfate is ________ M sodium ion and ________ M sulfate i
omeli [17]

Answer:

The concentration of species in 500 mL of a 2.104 M solution of sodium sulfate is 4.208 M sodium ion and 2.104 M sulfate ion.  (option E)

Explanation:

Step 1: Data given

Volume = 500 mL = 0.500 L

The concentration sodium sulfate = 2.104 M

Step 2: The equation

Na2SO4 → 2Na+ + SO4^2-

For 1 mol Na2SO4 we have 2 moles sodium ion (Na+) and 1 mol sulfate ion (SO4^2-)

Step 3: Calculate the concentration of the ions

[Na+] = 2*2.104 M = 4.208 M

[SO4^2-] = 1*2.104 M = 2.104 M

The concentration of species in 500 mL of a 2.104 M solution of sodium sulfate is 4.208 M sodium ion and 2.104 M sulfate ion.  (option E)

Answer:

The partial pressure is P_p= 737.5 mm \ of  \ Hg

Explanation:

The Partial pressure of H_2 is mathematically represented as

           P_p = P_T -P_w

Where P_T is the total pressure of water with a value of 15.5 mm of Hg

           P_w is the partial pressure of water with a value 753 mm of Hg

Now substituting values

          P_p = 753-15.5

               P_p= 737.5 mm \ of  \ Hg
