Question

the recommended adult dose of Elixophyllin ® , a drug used to treat asthma, is 6.00 mg/kg of body mass. Calculate the dose in milligrams for a 166-lb person. 1 lb = 453.59 g.

Answer 1

`\boxed{\text{452 mg}}`

Step-by-step explanation:

(a) Convert pounds to kilograms.

`\text{Mass} = \text{ 166 lb} * \frac{\text{453.59 g}}{\text{1 lb}} *\frac{\text{1 kg}}{\text{1000 g}} = \text{75.30 kg}`

(b) Calculate the dose

`\text{Dose} = \text{ 75.30 kg body mass} * \frac{\text{6.00 mg Elixophyllin}}{\text{1 kg body mass}} = \textbf{452 mg Elixophyllin}\\\text{The dose of Elixophyllin for a 166 lb person is $\boxed{\textbf{452 mg}}$}`
