Explanation:
The mass (in grams) of NaCl required to prepare the solution is 36.27 g
<h3>What is molarity?</h3>
Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>How to determine the mole of NaCl</h3>
- Volume = 200 mL = 200 / 1000 = 0.2 L
- Molarity = 3.1 M
- Mole of NaCl =?
The mole of NaCl in the solution can be obtained as follow:
Molarity = mole / Volume
Cross multiply
Mole = Molarity x Volume
Mole of NaCl = 3.1 × 0.2
Mole of NaCl = 0.62 mole
<h3>How to determine the mass of NaCl </h3>
We can obtain the mass of NaCl needed to prepare the solution as follow:
- Molar mass of NaCl = 58.5 g/mol
- Mole of NaCl = 0.62 mole
- Mass of NaCl = ?
Mole = mass / molar mass
Cross multiply
Mass = mole × molar mass
Mass of NaCl = 0.62 × 58.5
Mass of NaCl = 36.27 g

It takes the fatty proteins and liqwafizesees them
First of all, protein synthesis is translation not transcription. So I will take it that you just typed this wrong.
So, translation of mRNA into the protein ends at a step called termination. Termination happens when a stop codon in the mRNA (UAA, UAG or UGA) enters the A site. These stop codons are recognized by proteins called release factors which fit into the P site of the ribosome (note these are not tRNAs). These release factors mess with the enzyme that normally forms peptide bonds - and this then separates the chain from the tRNA and the newly made protein gets released. the small and large ribosomes then separate from eh mRNA and can go do another round of translation with another mRNA (good recycling!!).
