Explanation:
is this what u want???
Answer:
30.4 torr
Explanation:
We have all the information which is required to solve this question ( more than we even need as the molecular weight)
Ptotal = Ptoluene + Pbenzene
Ptotal = Xtoluene Pºtoluene + XbenzenePºbenzene
The mole fraction is given by the formula:
X =number of moles / total number of moles
Xtoluene = 8.53 / (2.15+8.53) = 0.80
Xbenzene = 2.15 / 10.68 = 0.20
⇒Ptotal = 0.80 x 14torr + 0.20 x 96 torr = 30.4 torr
The answer is A, I’m pretty sure, I remember learning this a few years ago, I hope you get it right :)
Answer:
It copies itself and gives instructions for building cells.
It provides energy to cells and passes from parent to offspring
Explanation:
The DNA is the genetic materials of the cell upon which any form of inheritance is predicated.
This giant molecules is a very important organelle in all living organisms. It has a double helix structure and can be found within the nucleus.
- The DNA copies itself and gives instruction for building cells.
- It has important information needed by the cell to produce protein so DNA replication is a vital process.
- The DNA is also able to ration energy within the cell.
- It passes genetic materials from parents to offspring
