Answer:
<h2>28,800 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 24 × 1200
We have the final answer as
<h3>28,800 g</h3>
Hope this helps you
Answer: The tree died 9709.46 years before.
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant = 100
a - x = amount left after decay process = 
a) to find rate constant
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
b) to know the age
The tree died 9709.46 years before.
