Algebra.Com's Answer #513332 by josgarithmetic(39618)![]() ![]() ![]() You can put this solution on YOUR website! Amount of salt will be the same before and after evaporation.\r \n" ); document.write( "\n" ); document.write( "Amount of salt is 16*(0.02).\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Amount of salt solution at the beginning is 16 ounces. Most of this is water, and some of it is salt. The WATER WILL DECREASE THROUGH EVAPORATION. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "At start, fraction of the solution being salt is \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "After the needed evaporation, the numerator is unchanged, but the denominator must be decreased; and the resulting fraction must equal 0.04.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "From that, do you know what to do? \n" ); document.write( " |
