A single tree produces about 2.6 x 102 lb f oxygen each year. The Amazon rainforest has about 3.9 x 1011 trees.
About how many ounces of oxygen are produced in the rain forest each day?
$$\frac{2.6*10^{2} lb\ Oxygen}{1\ year} * \frac{1\ year}{365.25\ days}*\frac{16\ ounces}{1\ lb} = 11.3894592744695414\ \frac{ounces\ Oxyegen}{day}$$
First, we have done some simple unit conversions to get 11.3894592744695414 ounces Oxygen/day.
Now, since 1 tree produces 11.3894592744695414 ounces Oyxgen/day...
This means that all we have to do is multiply 3.9*10^11 to 11.3894592744695414 ounces Oxygen/day to get our answer:
4,441,889,117,043.121146 ounces of Oxygen produced in the rain forest each day.
$$\frac{2.6*10^{2} lb\ Oxygen}{1\ year} * \frac{1\ year}{365.25\ days}*\frac{16\ ounces}{1\ lb} = 11.3894592744695414\ \frac{ounces\ Oxyegen}{day}$$
