Answer 1

Answer ) volume of solution (V) = 122 mil %m/y of sodium chloride = 5.58% %m - wt of sodium Chloride x 100 volume of solution wat of of sodium chloride = %m/yx volume of solution 100 5.58 x122 100 = 6.809 Note: According to HomeworkLib policy we have solve only 1st question but the 1st question has been alteady solved by you and it is correct so I did the next one.?
