Answer:
The number of mole is 0.04167mole
Explanation:
To convert gram to mole, we need to calculate the molecular weight of the compound
C6H12O6
C - 12
H - 1
O - 16
Molecular weight = 6 * 12 + 1 *12 + 6 * 16
= 72 + 12 + 96
= 180g/mol
To covert gram to mole
Therefore,
= 7.50g/ 180g/mol
= 0.04167 mole of glucose
Given :
Length , l = 59.8 m.
Breadth , b = 26.6 m.
Depth , d = 3.7 ft .
Density of water , 
.
To Find :
Mass of water in pool .
Solution :
First we will covert depth into m from ft .
For ,
So , volume of pool is :
We know , density is given by :
So , 
Putting given values in above equation :
Hence , this is the required solution.
Answer:
The total amount of energy before and after a chemical reaction is the same. Thus, energy is Question 14 options: the same as mass.
Explanation:
isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.
