Answer:
40
Step-by-step explanation:
The starting dose of Sodium Oxybate is 4.5 gm per night in two equally divided doses.
So, each divided doses of Sodium Oxybate will contain 4.5/2 =2.25 gm.
Now, a Sodium Oxybate oral solution is available in a 180 ml bottle that contains 50% w/v of Sodium Oxybate.
Hence, 50 gm of Sodium Oxybate will be there in 100 ml of the solution.
So, 50×180/100 =90 gm of Sodium Oxybate will be there in 180 ml of the solution.
Therefore, in each container of the oral solution, there will be 90/2.25 =40 divided doses are available. (Answer)
