Question 1022449
.
Suppose that 16 gallons of a 16% salt solution are mixed with 32 gallons of a 28% salt solution. What is the percent of salt in the resulting solution?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


The percent is


{{{(16*0.16 + 32*0.28)/(16+32)}}} . {{{100}}} = . . . 


Please calculate it yourself.


Notice that the concentrations here are measured in {{{kg/kg}}}, although the volumes of the solution are given in gallons.
