a solution contains 50g of common salt in 450g of water calculate the concentration of the solution in terms of mass by mass percentage,

mass of common salt =50g

mass of water =450g

total mass of the solution is 450 + 50 =500g

mass% =50/500*100 =10%

yes right.. 


mass of salt = 50g 


mass of water= 450 g

mass percentage= mass of the solute/ total mass of the solution

   = 50 / 450 + 50 *100

   = 50 / 500 *100 

   = 50/ 5 

   = 10 % ans.. .
