Answer:
1.2 liters.
Explanation:
Focus on the 4th digit: that's the ones column. The 3rd digit is the decimal place, just be sure to round up.
 
        
             
        
        
        
Mole is mass (g) / Molar mass (mole/gram) 
So to find mass in gram multiply the no.mole by Molar mass
        
                    
             
        
        
        
Answer: <em>Acceleration of the ball in the given system is 5 meter per Second Square</em>
<em>The laws of motion are used to determine various aspects of an object in motion</em>.
Explanation:
Applying the first law of motion to calculate acceleration; if formula used in first law is given as 
Here we have a final velocity as 40 meter per second and initial velocity as 20 meter per second and time span is given as 2 second applying the given values in the given equation and finding the value of a
                              
 
 
        
             
        
        
        
Explanation:
first you get moles of silver 
n=m/M
hence you add no of moles to this equation 
c=nv
v=n/c
