Answer : The age of the artifact is,
Explanation :
Half-life = 5715 years
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the time taken to decay.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = time taken by sample = ?
a = initial activity of the reactant = 58.2 counts per minute
a - x = activity left after decay process = 42.8 counts per minute
Now put all the given values in above equation, we get
Therefore, the age of the artifact is,
Answer:
D is the right answer
Explanation:
A has the wrong numbering, B has the wrong orbital order, C also has the wrong orbital order
%= total atomic mass of element/formula mass of the compoundX100
atomic mass(Ar) of sulfur- 32
Ar of Cu- 64
Ar of O-16
64+32+(16x4)= 160
32/160=0.2
0.2x100=20
20%
