Tems11 [23]

Answer:

b. 17,190

Explanation:

Using the formula for C-14 dating,

t=\dfrac{ln(\dfrac{N}{N_0})t_\frac{1}{2}  }{-0.693}

where Present Value N =1/8 of Parent Sample

Initial Value, N_0=1

Half Life, t_\frac{1}{2}=5730 years

t=\dfrac{ln(\dfrac{1/8}{1})5730}{-0.693}

=17,190

Therefore the fossil is about 17190 years old.

Isotope Atomic Mass (amu) Percent Abundance
exis [7]

Answer:

The average atomic mass is closer to Si- 28 because this isotope is present in more percentage in the sample.

Explanation:

Given data:

Atomic mass of silicon= ?

Percent abundance of Si-28 = 92.21%

Atomic mass of Si-28 = 27.98 amu

Percent abundance of Si-29 = 4.70%

Atomic mass of  Si-29 = 28.98 amu

Percent abundance of Si-30 = 3.09%

Atomic mass of  Si-30 = 29.97 amu

Solution:

Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)+(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass = (92.21×27.98)+(4.70×28.98)+(3.09×29.97) /100

Average atomic mass =  2580.04 +136.21+92.61 / 100

Average atomic mass = 2808.86 / 100

Average atomic mass  = 28.08amu.

The average atomic mass is closer to Si- 28 because this isotope is present in more percentage in the sample.
