Question

me pueden resolver esto por favor

Answer 1

1.  Solucion = soluto  + solvente

Solvente = solucion – soluto

Solvente = 110 g – 30 g = 80 g

% m/m = masa soluto / m solc. x 100

% m/m = 30 g / 110 g x 100

%m/m = 27.27

2.  % m/m = 11

  m solc. = 500 g

%m/m = m soluto / m solc. x 100

 

m soluto = %m/m x m solc.

                   ````````````````````

                              100

m = 11 g /g x 500 g

        ````````````````````

                  100

m = 55 g de soluto
