Grams. liters is liquid. meters is length and atm is idk
        
                    
             
        
        
        
Its running pressure in torr would be :
5.10 x 10^8 pa  x 1kPa/1000 Pa x 760 / 101.325 kPa
= 5.10 x 10 ^5  x   76 x 10^-1  x 1.01325 x 10 ^-2
= 392.7375 x 10^2
= 3.927275 x 10^4
ope this helps
        
                    
             
        
        
        
Answer:
Explanation:
Columns and rows used in the periodic classification of elements shows trends in the properties of elements. 
The periodic columns are called groups and they denote vertical arrangement of elements. 
The horizontal rows are the periods. 
- Groups and Periods provides a very simple way to classify elements. 
- They reflect trends among different elements that are found in nature. Following these groups and periods, it is even possible to predict the nature of an undiscovered element. 
- Certain parts of the table have some unique elements on them with some distinctive properties that distinguish them from others. 
- The atomic number is the basis of this classification. By this, it is possible to delineate that elements with similar properties are located on the same group.
