Answer: The 234.74 grams of sample should be ordered.
Explanation:
Let the gram of 114 Ag to ordered be ![N_o](https://tex.z-dn.net/?f=N_o)
The amount required for the beginning of experiment = 0.0575 g
Time requires to ship the sample = 4.2hour = 252 min(1 hr = 60 min)
Half life of the sample =
= 21 min
![\lambda =\frac{0.693}{t_{\frac{1}{2}}}=\frac{0.693}{21 min}=0.033 min^{-1}](https://tex.z-dn.net/?f=%5Clambda%20%3D%5Cfrac%7B0.693%7D%7Bt_%7B%5Cfrac%7B1%7D%7B2%7D%7D%7D%3D%5Cfrac%7B0.693%7D%7B21%20min%7D%3D0.033%20min%5E%7B-1%7D)
![\log[N]=\log[N_o]-\frac{\lambda t}{2.303}](https://tex.z-dn.net/?f=%5Clog%5BN%5D%3D%5Clog%5BN_o%5D-%5Cfrac%7B%5Clambda%20t%7D%7B2.303%7D)
![\log[0.0575 g]=\log[N_o]-\frac{0.033 min^{-1}\times 252 min}{2.303}](https://tex.z-dn.net/?f=%5Clog%5B0.0575%20g%5D%3D%5Clog%5BN_o%5D-%5Cfrac%7B0.033%20min%5E%7B-1%7D%5Ctimes%20252%20min%7D%7B2.303%7D)
![N_o=234.74 grams](https://tex.z-dn.net/?f=N_o%3D234.74%20grams)
The 234.74 grams of sample should be ordered.
Mass is the measure of the quantity of the substance present in the sample containing a compound or molecule. The mass of sucrose in the sample is 171 g.
<h3>What is mass?</h3>
The mass of the compound in the sample is the product of the number of moles of the substance and the molar mass of the compound.
Given,
The molar mass of the sucrose compound = 342.3 g/mol
Number of moles of sucrose = 0.500 moles
Mass of sucrose is calculated as:
![\begin{aligned}\rm mass &= \rm moles \times molar \; mass\\\\&= 0.500 \;\rm moles \times 342.3 \;\rm g/mol\\\\&= 171.15 \;\rm gm\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%5Crm%20mass%20%26%3D%20%5Crm%20moles%20%5Ctimes%20molar%20%5C%3B%20mass%5C%5C%5C%5C%26%3D%200.500%20%5C%3B%5Crm%20moles%20%5Ctimes%20342.3%20%5C%3B%5Crm%20g%2Fmol%5C%5C%5C%5C%26%3D%20171.15%20%5C%3B%5Crm%20gm%5Cend%7Baligned%7D)
Therefore, option A. 171 gm is the mass of sucrose.

Answer:
Hazardous types: This type poses potential threats to the environment and human life.Battery wastes from thrown away technology.
Electronic waste or e-waste describe discarded electrical devices. Used electronics which are destined for refurbishment, resale, salvage recycling through material recovery, or disposal are also considered e-waste.
