Where M₂ is the mass remaining, M₀ is the initial mass, and t is time in days.
Using the data given by the problem:
M₂ = 2.000 mg *
M₂ = 0.258 mg
Answer:
Explanation:
The number of molecules of KCN can be found by using the formula
<h3>N = n × L</h3>where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 0.00048 × 6.02 × 10²³
We have the final answer as
