Phosphoric acid, a mild acid used among other things as a rust inhibitor, food additive, and etching agent for cavity repair by dentists, can be made from elemental phosphorus in a two step process. In the first step, phosphorus and oxygen react to form diphosphorus pentoxide: →+P4s  5O2g  2P2O5g In the second step, diphosphorus pentoxide and water react to form phosphoric acid  H3PO4 : →+P2O5g  3H2Ol  2H3PO4l Suppose the yield of the first step is  66.%  and the yield of the second step is  62.% . Calculate the mass of phosphorus required to make  2.0kg  of phosphoric acid. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.

Question 25 of 97 Submit DDT was an insecticide used to prevent mosquito borne diseases. Due to the harmful effects on birds and fish, it is now banned in the US. However, other countries still use it to control mosquitos. It can be prepared by the reaction shown below.
