Concept explainers
(a)
Interpretation:
The quantity of phosphorus-32 should be calculated which remains from 1.00 g sample after 2 half-lives.
Concept Introduction:
The time which is required for a quantity to reduce to half of its initial value is known as half -life.
Or,
The time at which the reactant concentration is reduced to half of its initial concentration is known as half-life.
The expression for calculating amount left after decay of radioactive atom is shown as:
Where, t = number of half-lives that passed.
(b)
Interpretation:
The quantity of phosphorus-32 should be calculated which remains from 1.00 g sample after 4 half-lives.
Concept Introduction:
The time which is required for a quantity to reduce to half of its initial value is known as half -life.
Or,
The time at which the reactant concentration is reduced to half of its initial concentration is known as half-life.
The expression for calculating amount left after decay of radioactive atom is shown as:
Where, t = number of half-lives that passed.
(c)
Interpretation:
The quantity of phosphorus-32 should be calculated which remains from 1.00 g sample after 8 half-lives.
Concept Introduction:
The time which is required for a quantity to reduce to half of its initial value is known as half -life.
Or,
The time at which the reactant concentration is reduced to half of its initial concentration is known as half-life.
The expression for calculating amount left after decay of radioactive atom is shown as:
Where, t = number of half-lives that passed.
