Answer:
See explanation below
Explanation:
To solve this problem, we need to use the expression of half life decay of concentration (or mass) which is the following:
m = m₀e^-kt (1)
In this case, k will be the constant rate of this element. This is calculated using the following expression:
k = ln2/t₁/₂ (2)
Let's calculate the value of k first:
k = ln2/2.7 = 0.2567 d⁻¹
Now, we can use the expression (1) to calculate the remaining mass:
m = 8.1 * e^(-0.2567 * 2.6)
m = 8.1 * e^(-0.6674)
m = 8.1 * 0.51303
m = 4.16 mg remaining
It is 2 because if you have a chart that shown all the elements at the top left corner it would show a number and that is the atomic number
Anemia is essentially an iron deficiency so the element found in the liver preventing it would be Fe (iron).
Answer:
A
Explanation:
because number of particle = moles × 6.02 × 10^23
which gives the answer as an A
