A 28-kg child can consume a maximum of 23 children's acetaminophen tablets in an 8-h period without exceeding the safety-limit m

Nesterboy [21]

Answer:

(b)90mg/lb

Explanation:

The child can consume a maximum of 23 tablets with 80mg of acetaminophen, the total acetaminophen ingest is:

$23*80=1840mg$

This value is for 8 hours, 8 hours is 1/3 of one day. This means that the dose that can be consumed in 24 hours is 3 times 1840mg.

$1840*3=5520mg$

To obtain the maximum allowable dose in mg per pound of body weight, divide this last value by the weight of the child in pounds.

Conversion of units: $28Kg(\frac{2.20lb}{1Kg} )=61.6lb$

$\frac{5520}{61.6} =89.61\approx90mg/lb$

Korolek [52]

Given :

Some compounds :

$A)\ CH_3Cl\ B)\ CH_3I\ C)\ CH_3Br\ D)\ CH_4$ .

To Find :

Which of the following compounds has the most deshielded protons .

Solution :

Deshielded means nucleus whose chemical shift has been increased due to removal of electron density, magnetic induction, or other effects .

In simple words deshielding means the ability to shift protons .

Now , among Cl , I , Br and H . Cl is the most electron negative .

Therefore , deshielding will be more in $CH_3Cl$ .

Hence , this is the required solution .
