Answer:
50 g Sucrose
Explanation:
Step 1: Given data
- Concentration of the solution: 2.5%
Step 2: Calculate the mass of sucrose needed to prepare the solution
The concentration of the solution is 2.5%, that is, there are 2.5 g of sucrose (solute) every 100 g of solution. The mass of sucrose needed to prepare 2000 g of solution is:
2000 g Solution × 2.5 g Sucrose/100 g Solution = 50 g Sucrose
 
        
             
        
        
        
<u>Answer:</u> The amount of energy absorbed by water is 5390 Calories
<u>Explanation:</u>
To calculate the amount of heat absorbed at normal boiling point, we use the equation:

where,
q = amount of heat absorbed = ?
m = mass of water = 10 grams
 = latent heat of vaporization = 539 Cal/g
 = latent heat of vaporization = 539 Cal/g
Putting values in above equation, we get:

Hence, the amount of energy absorbed by water is 5390 Calories

 Answer:
Explanation:
To solve the problem, we must know the kind of compounds we are dealing with. 
For the first compound, P1 and second compound P2: 
                                 N                       O                         N                     O
Mass percent       64.17                 35.73                  47.23               52.79
Atomic mass           14                      16                         14                    16
Number of 
moles             64.17/14            35.73/16            47.23/14    52.79/16       
                             4.58                  2.23                      3.37                  3.30
Simplest
ratio                 4.58/2.23            2.23/2.23             3.37/3.30         3.3/3.3
                               2                           1                             1                        1
                               
P1 compound is N₂O
P2 compound is NO
These are the compounds, 
    In N₂O = 28:16
           NO = 14:16
This is the ratio of nitrogen to a fixed mass of oxygen for the two compounds.
