4. A gas occupies 1.56 L at 2.00 atm. What will be the volume of this gas if the pressure becomes 4.00 atm?
tekilochka [14]

Answer:

<u>0.78 L</u>

Explanation:

From Boyle's Law :

P₁V₁ = P₂V₂

Here :

  • P₁ = 2.00 atm
  • V₁ = 1.56 L
  • P₂ = 4.00 L

Solving :

  • V₂ = P₁V₁ / P₂
  • V₂ = 2 x 1.56 / 4
  • V₂ = 1.56 / 2
  • V₂ = <u>0.78 L</u>

rRNA: The function of rRNA is to join amino acids to the peptide bonds.

tRNA:  Delivers amino acids to the site of protein synthesis. It also has an anticodon that interact with specific codon of another nucleus.
