A student measures the volume of a solution to be 0.01370 have 5 significant digits in this measurement.
<h3>What are significant digits?</h3>
The significant digits are the minimum number from zero to nine for reporting any measurement where the digits are uncertain.
The significant digits starting from zero are not significant digits, decimal is not a significant digit, and ending zero after the decimal are significant digits.
Therefore, the student measures the volume of a solution to be 0.01370 5 significant digits are in this measurement.

Answer:

Explanation:
From the question we are told that:
Mass of mixture 
Mass of Barium 
Equation of Reaction is given as

Generally the equation for Moles of Barium  is mathematically given by
Since
  
Therefore

Answer:
it has 0g of sugar (hopes this helps)
 
        
                    
             
        
        
        
Answer:
Resistance 
Explanation:
Resistance is the measure of the opposition of current in a circuit. 
 
        
             
        
        
        
The density  is 3.144 g / cm^3.
<u>Explanation</u>:
If effective number of atom in NaCl type structure, z = 4
a = 705.2 pm ⇒ In centimeter = 705.2  10^-10
 10^-10
Na = 6.023  10^23
 10^23
density = (molecular weight) (z) / (Na) (a^3)
where molecular weight of KI is 166 g, 
            Z represents the atomic number
density = (molecular weight) (z) / (Na) (a^3)              
              = (166  4) / (6.023
 4) / (6.023  10^23)
 10^23)  (705.2
 (705.2  10^-10)
 10^-10)
density = 3.144 g / cm^3.
