Explanation:
The difference among mRNA, tRNA and rRNA are:
mRNA: It carries DNA's protein building information from nucleus to the cytoplasm. It is also read as codons nucleotide triplet that indicate specific amino acids .
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.
The similarity among mRNA, rRNA and tRNA is that they all consists of ribonucleic acid and can exist outside the nucleus in eukaryotes.
Q1)
molarity is defined as the number of moles of solute in 1 L of solution.
the NaCl solution volume is 1.00 L
number of moles NaCl = NaCl mass present / molar mass of NaCl
NaCl moles = 112 g / 58.5 g/mol = 1.91 mol
the number of moles of NaCl in 1.00 L of solution is - 1.91 mol
therefore molarity of NaCl is 1.91 M
Q2)
molality is defined as the number of moles of solute in 1 kg of solvent.
density is mass per volume.
density of the solution is 1.08 g/mL.
therefore mass of the solution is = density x volume
mass = 1.08 g/mL x 1000 mL = 1080 g
since we have to find the moles in 1 kg of solvent
mass of solvent = 1080 g - 112 g = 968 g
number of moles of NaCl in 968 g of solvent - 1.91 mol
therefore number of NaCl moles in 1000 g - (1.91 mol / 968 g) x 1000 g/kg = 1.97 mol/kg
molality of NaCl solution is 1.97 mol/kg
Q3)
mass percentage is the percentage of mass of solute by total mass of the solution
mass percentage of solution = mass of solute / total mass of the solution
mass of solute = 112 g
total mass of solution = 1080 g
mass % of NaCl = 112 g / 1080 g x 100%
therefore mass % of NaCl = 10.4 %
answer is 10.4 %
The best answer is Titanium
Answer:
The total pressure P = 1.642 atm
Explanation:
From the dalton's law
Total pressure of the mixture is
----- (1)
atm
atm
n = 0.24 mole
R = 
T = 41 °c = 314 K
= 0.634 atm
From equation (1)
P = 0.419 + 0.589 + 0.634
P = 1.642 atm
Thus the total pressure P = 1.642 atm
