When the temperature of an ideal gas rises from 27°C to 927°C, the root mean square speed of its molecules increases to four times its original level. Thus, the new v_(rms) becomes twice what it was initially.

An infant acetaminophen suspension contains 80 mg/0.80 mL suspension. The recommended dose is 15 mg/kg body weight.
KiRa [2933]

Response:

0.8853 mL

Clarification:

Initially, we convert 13 lb to kg, remembering that 1 lb = 0.454 kg:

  • 13 lb * \frac{0.454kg}{1lb} = 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
