Moles = mass / molar mass
molar mass of O2 is 32
therefore moles = 72/32
= 2.25 moles
Depends on the cut if its like a pimple You could use chap stick but if its a deep cut you should probably get it checked out/ use a lot of pressure and hold a clean rag over the cut. if its a little scrape clean it with alcohol and put some napkin over it and then a bandaid
Answer: The strength of an acid or alkali depends on the degree of dissociation of the acid or alkali in water. The degree of dissociation measures the percentage of acid molecules that ionise when dissolved in water. He could use universal indicators or litmus paper for this.

Given :
A mixture of water and acetone at 756 mm boils at 70.0°C.
The vapor pressure of acetone is 1.54 atm at 70.0°C, while the vapor pressure of water is 0.312 atm at the same temperature.
To Find :
The percentage composition of the mixture.
Solution :
By Raoult's law :
......( 1 )
Also , 
......( 2 )
Solving equation 1 and 2 , we get :
.
Mass of acetone ,
Mass of water ,
Hence , this is the required solution.
Answer:
A major function of the Endomembrane system is
The endomembrane system (endo- = “within”) is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins.
Explanation:
The endomembrane system (endo = “within”) is a group of membranes and organelles (Figure 4.4. 1) in eukaryotic cells that works together to modify, package, and transport lipids and proteins. The endomembrane system is a series of compartments that work together to package, label, and ship proteins and molecules. In your cells, the endomembrane system is made up of both the endoplasmic reticulum and the Golgi apparatus. These compartments are folds of membranes that form tubes and sacs in your cells.
Hoped this helped! :D
