Answer:
(a)The molar mass of the gene fragment is 18220.071g/mol = 18.22 kg/mol
(b)The freezing point for the aqueous solution is 
C
Explanation:
The osmotic pressure (π) is given by the following equation:
= Concentration of solution
R = universal gas constant = 62.364 
T = temperature
Weight of solute = w = 10.0 mg
Let the molecular weight of the solute be m g/mol.
Concentration = 
m = 18220.071g/mol
Therefore, the molar mass of the gene fragment is 18220.071g/mol = 18.22 kg/mol
m is the molality of the solution.
m = 
mol/kg
= 
C
The freezing point for the aqueous solution is C
Answer:
The binding energy of a mole of the nuclei is 252KJ
Explanation:
The binding energy is the amount of energy required to separate an atom into its nuclei.
From Einstein's relations,
E = Δm
where E is the energy, Δm is the mass defect and c is the speed.
The mole of nuclei moves with the speed of light, so that;
c = 3.0 × 
m/s
Given that Δm = 0.00084Kg/mol, the binding energy is calculated as;
E = 0.00084 × 3.0 ×
= 252000
= 252KJ
The binding energy of a mole of the nuclei is 252KJ.
A meander is best described as a bend or curve in a stream channel.
Ga, 31 electrons/ protons, 39 neutrons
Answer:
c. isotope number
Explanation:
Mass Number is the sum total of mass of protons and neutrons present in the nucleus of an atom. Generally they are being used in distinguishing isotopes. E.g Carbon - 12, Carbon - 13
Atomic Number is the number of protons. Every single element has it's unique atomic number and can be used in identification purpose. E.g Carbon - 6, Hydrogen - 1.
The correct option is option C. This is the symbol that is not necessary for the identification of a nuclide.
