Answer: Molarity increases
Explanation:
Molarity, also known as concentration in moles/dm3 or g/dm3, is calculated by dividing the amount of solute dissolved by the volume of solvent. So, Molarity (c) = amount of solute (n) / volume (v)
i.e c = n/v
Hence, molarity is directly proportional to the amount of solute dissolved, and inversely proportional to the volume of solvent.
Thus, at same volume, any increase in solute amount increases molarity while a decrease will also decreases molarity.

Explanation:
Answer:
2
Step-by-step explanation:
The formula for the most stable form of oxygen is O₂, so the subscript is 2.
However, there is a less stable form of oxygen called <em>ozon</em>e. Its formula is O₃, so the subscript for ozone is 3.
Answer:
![\large \boxed{32}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B32%7D)
Explanation:
![\text{Dosage rate} = \dfrac{\text{2.0 g}}{\text{6 h}}](https://tex.z-dn.net/?f=%5Ctext%7BDosage%20rate%7D%20%3D%20%5Cdfrac%7B%5Ctext%7B2.0%20g%7D%7D%7B%5Ctext%7B6%20h%7D%7D)
We must convert this measurement to units of "tablets per day".
1. Convert grams to milligrams
![\text{Mass} = \text{2.0 g} \times \dfrac{\text{1000 mg}}{\text{1 g}} = \text{2000 mg}](https://tex.z-dn.net/?f=%5Ctext%7BMass%7D%20%3D%20%5Ctext%7B2.0%20g%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B1000%20mg%7D%7D%7B%5Ctext%7B1%20g%7D%7D%20%3D%20%5Ctext%7B2000%20mg%7D)
2. Convert milligrams to tablets
![\text{No. of tablets} = \text{2000 mg} \times \dfrac{\text{1 tablet}}{\text{250 mg}} = \text{8.0 tablets}](https://tex.z-dn.net/?f=%5Ctext%7BNo.%20of%20tablets%7D%20%3D%20%5Ctext%7B2000%20mg%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B1%20tablet%7D%7D%7B%5Ctext%7B250%20mg%7D%7D%20%3D%20%5Ctext%7B8.0%20tablets%7D)
3. Convert hours to days
![\text{Time} = \text{6 h} \times \dfrac{\text{1 da}}{\text{24 h}} = \text{ 0.25 da}](https://tex.z-dn.net/?f=%5Ctext%7BTime%7D%20%3D%20%5Ctext%7B6%20h%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B1%20da%7D%7D%7B%5Ctext%7B24%20h%7D%7D%20%3D%20%5Ctext%7B%200.25%20da%7D)
4. Calculate the tablets per day
![\dfrac{\text{2.0 g}}{\text{6 h}} = \dfrac{\text{8.0 tablets}}{\text{0.25 da}} = \textbf{32 tablets per day}\\\\\text{The patient must take $\large \boxed{\textbf{32 tablets per day}}$}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7B2.0%20g%7D%7D%7B%5Ctext%7B6%20h%7D%7D%20%3D%20%5Cdfrac%7B%5Ctext%7B8.0%20tablets%7D%7D%7B%5Ctext%7B0.25%20da%7D%7D%20%3D%20%5Ctextbf%7B32%20tablets%20per%20day%7D%5C%5C%5C%5C%5Ctext%7BThe%20patient%20must%20take%20%24%5Clarge%20%5Cboxed%7B%5Ctextbf%7B32%20tablets%20per%20day%7D%7D%24%7D)
