C6H12O6 molar mass: 180.15768 g
solute: sugar
molarity = moles of solute / liters of solution
Jones Soda:
33 g / 180.15768 g = 0.18 moles C6H12O6
M = 0.18 g / 0.355 L
M = 0.52
Sierra Mist:
62 g / 180.15768 g = 0.34 moles C6H12O6
M = 0.34 g / 0.591 L
M = 0.58
Sienna Mist has a higher molarity and is more concentrated.

Answer:
The minimum number of boxes of pencils to be ordered is 630 boxes.
Explanation:
Since a pupil uses averagely 9.3 pencils
and a box contains 12 pencils,
the school enrollment is also 812
school's enrollment x average use of pencil per student
__________________________________________
             number of pencils in a box
812 x 9.3 = 7551.6 
7551.6 /12 = 629.3 
Having a total number of 630 boxes of pencils to be ordered.
 
        
             
        
        
        
Answer : The time passed in years is 
Explanation :
Half-life of carbon-14 = 5730 years
First we have to calculate the rate constant, we use the formula :



Now we have to calculate the time passed.
Expression for rate law for first order kinetics is given by:

where,
k = rate constant  = 
t = time passed by the sample  = ?
a = initial amount of the reactant disintegrate = 15.3 
a - x = amount left after decay process = 14.8
Now put all the given values in above equation, we get


Therefore, the time passed in years is
