A2-day-old infant who weighs 6 lb (2722 g) is fed formula every 4 hours. newborns require about 73 ml of fluid per pound (454 g) of body weight each day. in light of this information, approximately how much formula should the infant receive at each feeding?

The answer would be 72.94 ml/times

In this problem, the infant is fed for every 4 hours. Then, the frequency of feeding for a day would be: (24hours/day) / 4 (hours/times)= 6 times/ day.
The volume of feeding for a day that the infant need would be: 2722 g/(454 g/73ml)= 473.68ml
The number of milk for every fed would be: (473.68ml/day)/ (6 times/day)=  72.94 ml/times

If the experiment was perfomed more then once and you get the same results
