What volume is occupied by 8.67 grams of methane gas at STP?

1 answer:

8 0

Molar mass methane ( CH₄) = 16.04 g/mol

number of moles:

mass CH₄ / molar mass

8.67 / 16.04 => 0.5405 moles

1 mole ------------------ 22.4 L ( at STP )
0.5405 moles --------- ??

0.5405 x 22.4 / 1 => 12.1072 L

hope this helps!

Answer:

Most substituted alkene is produced as a major product

Explanation:

Dehydration of 3-methyl-2-butanol proceeds through E1 mechanism to form alkenes.
Most substituted alkene is produced as major product because of presence of highest number of hyperconjugative hydrogen atoms corresponding to the produced double bond (Saytzeff product).
Here, a H-shift also occurs in one of the intermediate step during dehydration to produce more stable tertiary carbocation.
Reaction mechanism has been shown below.
