If 33.6 g of kcal are dissolved in 192 g of water, what is the concentration of the solution in percent by mass?
Sav [38]
To  calculate  the  Percentage  by  mass  of  KCl  that   dissolve  in   water  is  calculated   as
   first getting  the  total  mass   of  KCl  and  that  of  water
 that  is   33.6 + 192=225.6grams
the  percentage  by  mass  is  therefore  calculate  as  The  mass  of  KCl  divided  by   total  multiply  by  100

that  is  (33.6/225.6) x100=14.9%

Explanation:

Since you're 16, you have to calculate how many seconds you've lived.

16 years × 31,536,000= 504,576,000 pennies.
