11eab929_2a4f_770e_99e6_db91cd0e0742_TB4470_11 is equivalent to 1.1 kilogram (kg) or 1100 grams (g). Therefore, if the person lost 1.1 kg in a week, the amount lost in µg/s can be calculated as: (1.1 kg/week) × (1000 g/kg) × (1,000,000 µg/g) ÷ (7 days/week) ÷ (24 hours/day) ÷ (60 min/hour) ÷ (60 s/min) Simplifying this expression gives approximately 2629.03 µg/s, which can be written in scientific notation as 2.6 × 10³ μg/s. Therefore, the best choice is A.
