As people are always dying and babies are always being born so doctors don’t know the exact figure of the population, just an estimate.
hope this helps x
Answer: 26.76%
Explanation:
A 100ml vial of 25% solution means that 25% of the total mass of the solution is the mass of the medication (solute).
Assuming a 100ml vial contains 100g of solution, then,
Mass of solute = 0.25 x 100g = 25g
For a 250ml solution, solute will be;
(250x25)/100 = 62.5g
Adding an additional 6g of medication makes it
62.5 + 6 = 68.5g
For a 250ml solution, the original mass is (250x100)/100 = 250g
With addition of 6g medication it becomes 256g
Solution after adding medication becomes 68.5/256 x 100%
= 26.76%
Diseases, mainly autoimmune, depression, anxiety, a sickness such as a cold or fever, or even just a lack of motivation not linked to depression can be reasons people decrease their physical activity level.
