fermium - 253 has a half - life of three days. a sample contains 400 g. use the formula $f(d)=400(0.794)^d$. how many grams of fermium will remain after twenty - three days?

Answer

Explanation:

Step1: Identificar el valor de d

El número de días es 23, entonces $d = 23$.

Step2: Sustituir d en la fórmula

Sustituimos $d = 23$ en $f(d)=400(0.794)^{d}$. Tenemos $f(23)=400\times(0.794)^{23}$.

Step3: Calcular el resultado

Calculando $(0.794)^{23}\approx0.00207$, luego $f(23)=400\times0.00207 = 0.828$.

Answer:

$0.828$ g
