द्रव्यमान प्रतिशत के रूप में उस विलयन के सांद्रण की गणना करें जिसके 150 g जल में 10g पोटेशियम नाइट्रेट घुला हुआ है।

Given, mass of potassium nitrate = 10g mass of solution = 150g We need to find the concentration of the solution in terms of mass percentage. Let the concentration of the solution be x%. It means, there are x grams of potassium nitrate in 100 grams of the solution. Step 1: Calculate the mass of potassium nitrate in 150g of the solution. $Massofpotassiumnitrate=\frac{x}{100}\times 150$ Step 2: As given, mass of potassium nitrate in the solution is 10g. $\frac{x}{100}\times 150=10$ Step 3: Simplifying the above equation. $x=\frac{10}{1.5}$ Step 4: Converting the above result into percentage. $x=\frac{10}{1.5}\times 100\%$ Step 5: Simplifying the above equation. $x=6.25\%$ Therefore, the concentration of the solution in terms of mass percentage is 6.25%.
