Answer:
there are 18.65 grams of sodium nitrate dissolved in 126 grams of the solution that is 14.8% by mass of the compound.
Step-by-step explanation:
To find the mass of sodium nitrate dissolved in the solution, we can use the concept of percent composition.
First, we need to determine the mass of the solution that is made up of sodium nitrate. Since the solution is 14.8% by mass of the compound, we can calculate this by multiplying the total mass of the solution by the percentage:
Mass of sodium nitrate in solution = (14.8/100) * 126 g
Mass of sodium nitrate in solution = 18.65 g
Therefore, there are 18.65 grams of sodium nitrate dissolved in 126 grams of the solution that is 14.8% by mass of the compound.
