Answer:
(b)90mg/lb
Explanation:
The child can consume a maximum of 23 tablets with 80mg of acetaminophen, the total acetaminophen ingest is:
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.
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:

You'll need to react 7,5 moles of Sodium with sulfuric acid to produce 3.75 moles of sodium sulfate
</span>
First of all, you need to balance the reaction. The balanced reaction is shown below (ensuring that the Law of Conservation of Mass is met on both sides):
2Na + H₂SO₄ → Na₂SO₄ + H₂
Now, all that you have to do is to use molar equivalences in this reaction applying the coefficients to calculate the moles of Sodium that you'll need:
Have a nice day!
