The Empirical formula of compound is C₁H₂O₁. The Molecular Formula of the compound is 4 (C₁H₂O₁).
<h3>What is Empirical Formula ?</h3>
Empirical formula is the simplest whole number ratio of atoms present in given compound.
Element % Atomic mass Relative no. of atoms Simplest whole ratio
C 40.6 12 
= 3.3 
H 5.1 1 
= 5.1 
O 54.2 16 
= 3.3
The Empirical formula of compound is C₁H₂O₁ or CH₂O
<h3>How to find the Molecular formula of compound ?</h3>
Molecular formula = Empirical formula × n
= 4
Molecular formula = n × Empirical formula
= 4 (C₁H₂O₁)
Thus from the above conclusion we can say that The Empirical formula of compound is C₁H₂O₁. The Molecular Formula of the compound is 4 (C₁H₂O₁).

Answer:
C) C₆H₁₂O₆.
Explanation:
- We can determine the molecular formula by calculating the molecular mass of different choices.
Molecular mass = ∑(no. of atoms * atomic mass).
A) CH₂O:
molecular mass = atomic mass of C + 2*atomic mass of H + atomic mass of O = (12.0 g/mol) + (2 * 1.0 g/mol) + (16.0 g/mol) = 30.0 g/mol.
B) C₃H₈O₃:
molecular mass = 3(atomic mass of C) + 8(atomic mass of H) + 3(atomic mass of O) = 3(12.0 g/mol) + 8(1.0 g/mol) + 3(16.0 g/mol) = 92.0 g/mol.
C) C₆H₁₂O₆:
molecular mass = 6(atomic mass of C) + 12(atomic mass of H) + 6(atomic mass of O) = 6(12.0 g/mol) + 12(1.0 g/mol) + 6(16.0 g/mol) = 180.0 g/mol.
D) C₈H₁₆O₈:
molecular mass = 8(atomic mass of C) + 16(atomic mass of H) + 8(atomic mass of O) = 8(12.0 g/mol) + 16(1.0 g/mol) + 8(16.0 g/mol) = 240.0 g/mol.
<em>So, the right choice is: C) C₆H₁₂O₆.</em>

Answer:
b. Bakelite
Explanation:
Bakelite -
Bakelite is a form if plastic , and is the very first plastic synthesized .
The handles of the cooking utensils are used to hold the utensil firmly , and hence need not turn hot while cooking , and need to be strong enough to take care of the food .
Hence , the handle should be of the material which is poor conductor of heat and strong .
Hence , bakelite is used for making the handle.
Answer:
Which statement best compares a eukaryote and a prokaryote?
A. Eukaryotes have a cell wall, while prokaryotes have a cell membrane.
*B. Eukaryotes have membrane-bound organelles, while prokaryotes have few specialized
structures.
C. Eukaryotes use active transport to move substances across the cell membrane, while
prokaryotes use facilitated diffusion.
D. Eukaryotes use flagella to move themselves through substances, while prokaryotes are not
able to move.
Explanation: its B
Hey there!
5 moles will be produced.
N₂ has a molar mass of 28.014 g/mol.
Convert 70g to mol:
70 ÷ 28.014 = 2.5
In N₂ there are 2 nitrogen atoms. In NH₃ there is 1 nitrogen atom.
So, there will be twice as many moles of NH₃ because every one molecule of N₂ will produce two molecules of NH₃.
2.5 x 2 = 5 moles
Hope this helps!
