<u>Step 1: Define</u>

CuClO₃

<u>Step 2: Find MM</u>

Molar Mass of Cu - 63.55 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of CuClO₃ - 63.55 + 35.45 + 3(16.00) = 147.05 g/mol

Iron-59 is a beta emitter with a half-life of 44.5 days. If a sample initially contains 180 mg of iron-59, how much iron-59 is l
Jobisdone [24]

Answer:

2.79 mg iron-59 is left in the sample after 267 days.

Explanation:

Given that:

Half life = 44.5 days

t_{1/2}=\frac {ln\ 2}{k}

Where, k is rate constant

So,  

k=\frac {ln\ 2}{t_{1/2}}

k=\frac {ln\ 2}{44.5}\ days^{-1}

The rate constant, k = 0.0156 days⁻¹

Using integrated rate law for first order kinetics as:

[A_t]=[A_0]e^{-kt}

Where,  

[A_t] is the concentration at time t

[A_0] is the initial concentration  = 180 mg

Time = 267 days

So,  

[A_t]=180\ mg\times e^{-0.0156\times 267}

[A_t]=180\times e^{-0.0156\times 267}\ mg

[A_t]=2.79\ mg

<u>2.79 mg iron-59 is left in the sample after 267 days.</u>
