Algebra.Com's Answer #73935 by Fombitz(32388)![]() ![]() You can put this solution on YOUR website! One virus takes up 8.5E-14 cc (cubic centimeters). N viruses take up 28 cc. Assuming that the viruses stack together and fill all of the space, set up a ratio. \r \n" ); document.write( "\n" ); document.write( "Volume of one virus / One virus = Volume of N viruses / N viruses\r \n" ); document.write( "\n" ); document.write( "Or using the information given, \r \n" ); document.write( "\n" ); document.write( "8.5E-14 cc/1 virus = 28 cc/N (viruses)\r \n" ); document.write( "\n" ); document.write( "Rearranging, by multiplying both sides by N and dividing by 8.5E-14, you get,\r \n" ); document.write( "\n" ); document.write( "N = 28/8.5E-14 = 3.3E14 viruses. \n" ); document.write( " |
