A law in Chemistry ; the elements when arranged in the order of thier atomic numbers show periodic varation of the autmoic structure and of their most properties - Also know as the Mendeleev's Law
It will be day time and the other side will be night time
Find 1 mol
6C = 12*6 = 72
12H=1*12 = 12
O6 = 16*6 = 96
Total = 180 grams
0.98 mol
0.98 * 180 = 176.40 My answer would have to go out to 176.40
Note: anyone responding will use rounded numbers for the atomic mass. All periodic tables have variations in them. Use your periodic table to get the better atomic mass.
Answer
176.40 g C6H12O6 <<<<

B.
Explanation:
The front vent of a fume hood that assists and maintain proper air circulation is <u>Airfoil</u>
<u />
The horizontal flat surface area of the fume hood where experiments are being carried out is <u>Work Surface.</u>
<u />
The main characteristics which demonstrate and describes how substances evaporate rapidly and readily into the thin air while producing a huge amount of vapor is known as <u>Volatile</u>
<u></u>
In front of the fume hood, lies the glass panel whose main purpose is to shield the user from the hazardous substance. This glass panel is known as the<u> Sash.</u>
If 20. 3 grams of an aqueous solution of iron(ii) chloride contains 2. 71 grams of iron(ii) chloride, then percentage by mass of iron(ii) chloride in the solution is 13.34%
Calculation,
Given:
mass of an aqueous solution of iron(ii) chloride = 20. 3 grams
mass of iron(ii) chloride = 2. 71 grams
The percentage by Mass is equal to percentage of mass of solute present in total mass of solution. It is also known as Mass percentage.
percentage by Mass = 100× 2. 71 grams/20. 3 grams = 13.34%
Hence, the percentage by mass of iron(ii) chloride in the solution is 13.34% .
