What is the mass percent of sucrose in a solution obtained by mixing 225.0 g of an aqueous solution that is 6.25% sucrose by mass with 135.0 g of an aqueous solution that is 8.20% sucrose by mass?

Answer:

#"Mass %"="Mass of solute"/"Mass of solution"xx100%#

Explanation:

And from the initial solutions, we have to first extract the mass of solute, and then divide this by the combined mass of solutions. And thus we go thru the arithmetic:

#(6.25%xx225.0*g+8.20%xx135.0*g)/(225.0*g+135.0*g)xx100%#

#~=7.0%#
