Copper is a trace element and nutrient in the diet of newborn babies, who require 80.0 μg per kg of body weight per day. Formula contains 0.48 μg/mL. How many mL of formula does a 6.60 lb baby require per day?

498.95 ml of formula per day

Explanation:

Baby body requirement of copper per day = 80.0. μg per Kg

Copper content of formula = 0.48 μg/mL.

Mass of baby = 6.60 lb

1 lb = 0.4536 Kg

6.6 lb = 2.9937 Kg

Therefore baby needs

80μg/Kg/day * 2.9937 Kg = 239.5μg/day of formula

But formula contains 0.48 μg/mL that means baby needs

(239.5 μg/day) : 0.48 μg/mL = 498.95 ml of formula per day

498.95 ml/day
