Answer
a. 20. g of mannitol are given in 1 h.
b. The patient receives 240 g of mannitol in 12 h.
Work Step by Step
a.
$20.\%$ (m/v) $ mannitol $ solution : $$ 20. \space g \space mannitol = 100 \space mL \space solution$$
$$100. \space mL \space solution \times \frac{20. \space g \space mannitol}{100 \space mL \space solution} = 20. \space g \space mannitol $$
b. According to the answer for 9.53a:
$1 \space h = 20. \space g \space mannitol$
$$12 \space h \times \frac{20. \space g \space mannitol}{1 \space h} = 240 \space g \space mannitol$$
