You HAVE TO know that molarity (M) tells you the number of moles of a solute per Liters of solution. 
M=mol/L 
0.3M = 2.7 mol/ Volume 
Volume = 2.7 mol/3.0 L 
Volume = 0.9 L
        
                    
             
        
        
        
If the moon did not rotate we would see all hemispheres of the moon as it revolves around the Earth and not just the phases.
        
             
        
        
        
Answer:
The physical states that are represented by each graph region are the liquid and the solid, the highest temperature is the liquid and as it freezes it becomes a solid. The particles change because when it's a liquid, it isn't that compact it's just spreading smootly but as it freezes the atoms start to stick together and become compact.

Hope that made sense!
 
        
             
        
        
        
Answer:
v = 658.82 km/h
Explanation:
The distance between New York and London is 
Time taken from New York to London is 8.5 hours
We need to find the average speed of the plane.
Total distance covered divided by the total time taken is equal to the average speed of an object. So,

So, the average speed of the plane is 658.82 km/h.
