Answer : The pH of a solution is, 7.28
Solution : Given,
Concentration of hydronium ion, 
= 
pH : It is defined as the negative logarithm of hydronium ion concentration or hydrogen ion concentration.
![pH=-\log [H_3O^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH_3O%5E%2B%5D)
Now put the value of hydronium ion concentration in this expression, we get the pH of the solution.
Therefore, the pH of a solution is, 7.28
Deoxygenated Blood enters and leaves the right side of the heart then Oxygenated blood enters and leaves the left side of the heart
In order to compute the mass of each solute in the sample, we simply multiply the percentage mass of each solute with the total mass of the solution. This is ad such:
Mass (NaCl) = 0.0486 x 294
Mass (NaCl) = 14.29 grams
Mass(Na₂CO₃) = 0.0754 x 294
Mass(Na₂CO₃) = 22.17 grams
