to make a saturated solution of 25g of sodium cholride is disoved in 7

1.	to make a saturated solution of 25g of sodium cholride is disoved in 75g of water at 293k what is the mass percent
Answer» GIVEN:- $\rm{Mass\:of\:Solute=25g}$ $\rm{Mass\:of\:Solvent=75g}$ TO FIND:- $\rm{Mass\: Percentage\:of\:Solution}$ FORMULAE USED:- ${\boxed{\rm{Mass\: Percentage=\dfrac{Mass\:of\:Solute}{Mass\:of\:Solution}\times{100}}}}$ EXPLANATION:- We know, $\rm{Mass\:of\:Solution=Mass\:of\:Solute+Mass\:of\:Solvent}$ $\rm{Mass\:of\:Solution=25g+75g}$ $\rm{Mass\:of\:Solution=100g}$ Now, Mass percentage of Solution $\implies\rm{\dfrac{Mass\:of\:Solute}{Mass\:of\:Solution}\times{100}}$ $\implies\rm{\dfrac{25}{100}\times{100}}$ $\implies\rm{\dfrac{25}{\cancel{100}}\times{\cancel{100}}}$ $\implies\rm{25 Percent.}$ . Hence, The mass Percentage of Solution is 25%. EXTRA INFORMATION. When no more solution can not be dissolved in given solution at given TEMPERATURE. It is called Saturated solution. if the AMOUNT of Solute contained in a solution LESS than the saturation level,it is called Unsaturated solution.
