Answer:
C₄H₄N₂
Explanation:
Given that:
M+ = 80.
It implies that the number of nitrogen present in the molecule must also be even according to the Nitrogen rule.
So from the Formula CHN, the nitrogen will have to be 2 because if we make use of 4, it will exceed the given M+ which is 80.
∴
C₄ = 4 × 12 = 48
H₄ = 4 × 1 = 4
<u>N₂ = 2 × 14 = 28 </u>
<u> 80 </u>
As such, the molecular formula of the compound is C₄H₄N₂
Answer:
Compound 3 is a clear liquid with a strong pleasantly fruity smell. If cooled it freezes at about −10°C. In the solid state it does not conduct electricity. ... It dissolves slightly in water, and a solution of 2g in 100mL of water doesn't change the electrical conductivity of the water.
Answer:
1.25 moles of CH4 TO THE above equation
Answer:
22.5%
Explanation:
To find percentage by mass, you divide the mass of the solute by the mass of the solvent.
5.08 g/22.6 g = 0.2248 = 22.5%
