Explanation:
To calculate that you need to know the value of the Kps (constant of solubility) at 30°C of KBr in water.
<u>When the product of the concentrations of both ions (Br- and K+) equals the Kps, the solution is saturated. </u>
Given the disociation of the salt in water:
The concentration of both ions are equal (1:1 ratio) and the same as the concentration of KBr added.
The Kps:
![Kps=[K^+][Br^-]](https://tex.z-dn.net/?f=Kps%3D%5BK%5E%2B%5D%5BBr%5E-%5D)
![[KBr]=(Kps)^{1/2}](https://tex.z-dn.net/?f=%5BKBr%5D%3D%28Kps%29%5E%7B1%2F2%7D)
[KBr] are <u>moles of the salt per litre of water</u>
Assuming a density of water of 1 g/cm3, 100 g are 0.1 litre
To calculate the mass:
![m=[KBr]*M*0.1 litre](https://tex.z-dn.net/?f=m%3D%5BKBr%5D%2AM%2A0.1%20litre)
where M is the molecular weight of the salt.
Answer:
unsaturated fats, which are liquid at room temperature,are different from saturated fat because they contain one or more double bonds and fewer hydrogen atoms on their carbon chain.
Answer:
Amine
Explanation:
The functional groups contained in Taxol are :
Ketone , Ester, Amide and Alcohol
while the functional group that is not contained in the Taxol is Amine
Taxol is a very potent anti-cancer chemotherapeutic, and it is also groped into a class called Taxanes and this makes it effective in the treatment of breast and ovarian cancer.
