Question

There are two quantities of salt solution: 80g and 120g. In the first solution there are 12g of salt, in the second solution there are 15g of salt. What is the concentration (in percent) of salt in each solution? What would be the concentration if we were to mix these solutions?

    80 g……..12 g salt
    120 g……..15 g salt

    I. 12/80=0.15=15/100= 15 % 
    II. 15/120=0,125= 125/1000=12,5 /100=12,5 %

    if you werw to mix these solutions
    120+80=200 g solutions
    12+15=27 g salt
    27/200=13,5/100= 13.5 %
