Question

The oxygen saturation level of a river is found by

dividing the amount of dissolved oxygen the river
water currently has per liter by the dissolved oxygen
capacity per liter of the water and then converting to a
percent. If the river currently has 7.3 milligrams of dis-
solved oxygen per liter of water and the dissolved
oxygen capacity is 9.8 milligrams per liter, what is the
oxygen saturation level, to the nearest percent?
