Answer
The patient receives 20. g of amino acids in 1 day.
Work Step by Step
1. The patient receives the dose of the 250 mL solution twice a day. Therefore: 1 day = 2 doses
$\frac{1 \space day}{2 \space doses}$ and $\frac{2 \space doses}{1 \space day}$
2. As we have calculated in 9.42a, one 250 mL dose of that solution has 10. g of amino acids. 1 dose = 10. g of amino acids
$\frac{1 \space dose}{10. \space g \space of \space amino \space acids}$ and $\frac{10. \space g \space of \space amino \space acids}{1 \space dose}$
3. Calculate the total mass of amino acids in 1 day:
1 day $\times \frac{2 \space doses}{1 \space day} \times \frac{10. \space g \space of \space amino \space acids}{1 \space dose} = 20. \space g \space of \space amino \space acids$
