A 0.89% (w/v) sodium chloride solution is referred to as physiological saline solution because it has the sameconcentration of s
alts as human blood. What is the molarity of a physiological saline solution?
1 answer:
Answer: Molarity of a physiological saline solution is 0.15 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

n = moles of solute
=volume of solution in ml
Given : 0.89 g of sodium chloride in 100 ml of solution.
To calculate the moles, we use the equation:

Volume of solution = 100 ml

Molarity of physiological saline solution is 0.15 M

Answer:
option b is the correct answer
Global warming, the hole inside the atmosphere in Oklahoma , california .
moles NaOH = c · V = 0.2432 mmol/mL · 24.75 mL = 6.0192 mmol
moles H2SO4 = 6.0192 mmol NaOH · 1 mmol H2SO4 / 2 mmol NaOH = 3.0096 mmol
Hence
[H2SO4]= n/V = 3.0096 mmol / 38.94 mL = 0.07729 M
The answer to this question is [H2SO4] = 0.07729 M
