Title: A sample of water that is 99.9999 percent pure contains 0.0001 percent impuritie Post by: einsteindude on Nov 29, 2014 A sample of water that is 99.9999 percent pure contains 0.0001 percent impurities. Consider from Chapter 1 that a glass of water contains on the order of a trillion trillion (1 × 1024) molecules. If 0.0001 percent of these molecules were the molecules of some impurity, about how many impurity molecules would this be?
A) 1000 (one thousand: 1 × 103) B) 1,000,000 (one million: 1 × 106) C) 1,000,000,000 (one billion: 1 × 109) D) 1,000,000,000,000,000,000 (one million trillion: 1 × 1018) Title: Re: A sample of water that is 99.9999 percent pure contains 0.0001 percent impuritie Post by: bSharp on Dec 3, 2014 Content hidden
