silver has an atomic mass of 107.868 amu. silver has two common isotopes. one of the isotopes has a mass of 106.906 amu and a re
Sunny_sXe [5.5K]

A. The abundance of the 2nd isotope is 48.119%

B. The mass of the 2nd isotope is 108.905 amu

Let the 1st isotope be A

Let the 2nd isotope be B

A. Determination of the abundance of the 2nd isotope

Abundance of isotope A = 51.881%.

<h3>Abundance of isotope B =? </h3>

Abundance of B = 100 – A

Abundance of B = 100 – 51.881

<h3>Abundance of B = 48.119%</h3>

B. Determination of the mass of the 2nd isotope

Atomic mass of silver = 107.868 amu.

Mass of 1st isotope (A) = 106.906 amu

Abundance of isotope A (A%) = 51.881%.

Abundance of isotope B (B%) = 48.119%

<h3>Mass of 2nd isotope (B) =? </h3>

atomic \: mass =  \frac{mass \: of \:A \times \:A\%}{100}  + \frac{mass \: of \:B \times \:B\%}{100} \\  \\ 107.868 = \frac{106.906\times \ \: 51.881}{100}  + \frac{mass \: of \:B \times \:48.119}{100} \\  \\ 107.868 = \: 55.464 + 0.48119 \times mass \: of \:B  \\  \\  collect \: like \: terms \\  \\ 0.48119 \times mass \: of \:B  = 107.868  - 55.464  \\  \\ divide \: both \: side \: by \: 0.48119 \\  \\ mass \: of \:B  = \frac{107.868  - 55.464 }{0.48119}  \\  \\ mass \: of \:B  =108.905 \: amu \\  \\

Therefore, the mass of the 2nd isotope is 108.905 amu

What is it called when an enzyme changes shape
7nadin3 [17]

Answer: Induced Fit

Explanation: The process wherein the enzymes change their shape is called as induced fit. It is the precision aligning of enzymes essential for catalytic activity which is caused by the binding of the substrate as enzymes possess active sites. Hence, as the substrate approaches the enzymes, the enzyme alters its shape.
