An infant acetaminophen suspension contains 80 mg/0.80 mL suspension. The recommended dose is 15 mg/kg body weight.
1 answer:
Response:
0.8853 mL
Clarification:
Initially, we convert 13 lb to kg, remembering that 1 lb = 0.454 kg:
- 13 lb *
= 5.902 kg
Next, we determine the required mg of acetaminophen to administer, applying the recommended dosage and infant's weight:
- 15 mg/kg * 5.902 kg = 88.53 mg
Finally, we compute the necessary mL of suspension, utilizing its concentration:
- 88.53 mg ÷ (80 mg/0.80 mL) = 0.8853 mL

Answer:- 64015 J
Solution: The calorimeter contains 4250 mL of water, which is at a temperature of 22.55 degrees Celsius.
The water's density is 1 gram per mL.
Thus, the mass of water = = 4250 grams.
After introducing the hot copper bar, the final temperature of the water reaches 26.15 degrees Celsius.
Thus, for the water = 26.15 - 22.55 = 3.60 degrees Celsius.
The specific heat capacity of water is 4.184 .
To determine the heat absorbed by the water, we can use the following formula:
where q represents heat energy, m refers to mass, and c indicates specific heat.
Now let's substitute the values into the equation to perform the calculations:
q = 64015 J
Therefore, the water absorbs 64015 J of heat.
