Asoft drink contains 11.5% sucrose (c12h22o11) by mass. how much sucrose, in grams, is contained in 355 ml (12 oz) of the soft drink? (assume a density of 1.04 g/ml.)

In  chemistry  concentration  is  equal  to  mass  of  the    substance  divided  by    volume. Therefore   mass is  equal  to  concentration  multiplied by  voiume
  that  is
355ml  x104ml=369.2g
  in   a  soft  drink  that   contain  11.5% of  sucrose  by  mass s  therefore
369.2g x 11.5/100=42.46g
