Question

some doctors reccomend that men drink 3 liters of water every day there are approximately 29.6 milliters in 1 fluid ounce wich measurement is closest to the number of fluid ounces in 3 liters

Answer 1

There are no answer options provided. But the answer should be 101 oz to 3 sig figs

Step-by-step explanation:

Water consumption: 3 liters/day

We are told that there are 29.6 ml in a fluid ounce. We can make that a conversion factor: (1 oz/29.6ml).

We can use this conversion factor to find the number of fluid ounces in 3 liters, once we recognize the need for a second conversion factor. The conversion we can make with the factor we have thus far is:

(3 liters)*(1oz/29.6 ml) = oz [but note that the volume units do not cancel]

We need a second conversion factor that relates liters and ml:

(1,000 ml/1 Liter)

Now add this to the expression above:

(3 liters)*(1oz/29.6 ml)*(1,000 ml/1 Liter)

Now both Liters and ml cancel, leaving just ounces.

(3)*(1oz/29.6)*(1,000) = 101.3 ounces

101 oz to 3 sig figs
