By weight, liquid A makes up 7.0 percent of solution I and 14.5 percent of solution II.
\n" ); document.write( "If 3 grams of solution I is mixed with 2 grams of solution II, then liquid A accounts for what percent of the weight of the resulting solution?
\n" ); document.write( "--------
\n" ); document.write( "Equation::
\n" ); document.write( "liq a + lig a = log a
\n" ); document.write( "---------------------------
\n" ); document.write( "0.7*3 + 0.145*2 = x(3+2)
\n" ); document.write( "-----
\n" ); document.write( "Multiply thru by 1000 to get::
\n" ); document.write( "700*3 + 145*2 = 5000x
\n" ); document.write( "----
\n" ); document.write( "2100 + 290 = 5000x
\n" ); document.write( "x = 2390/5000
\n" ); document.write( "x = 0.478 = 47.8% (% of liquid A in the mixture)
