Answer:
Explanation:
The formula for sodium is Na. It does not form a molecule in some way.
1 mol Na = 6.02*10^23 atoms
3.91 mol = x                                    Cross multiply
x = 3.91 * 6.02 * 10^23
x = 23.65 * 10^23
x = 2.365 * 10^24
Scientific notation is always expressed as a number 1 ≤ x < 10
 
        
             
        
        
        
It’s the third one because Cl has 17 protons bc of the numeric number and 18 electrons bc it’s always the opposite and 18 neutrons because you subtract 35-17=18
        
             
        
        
        
Answer:
The minimum concentration of acetaminophen that can be detected by new= 10μg/mL
Volume of blood sample=2ml
Minimum mass of acetaminophen that can be detected by automated system= 10×2= 20μg= 0.020mg
