Calculate the 48.2% by mass of KBr solution

Answer 1

To calculate the mass of KBr in a solution that is 48.2% by mass, you can use the formula:

Mass of KBr = (Percentage composition/100) x Total mass of solution

Let's assume we have a total mass of the solution as 100g. Then, the mass of KBr in the solution would be:

Mass of KBr = (48.2/100) x 100g = 48.2g

Therefore, in a 100g solution that is 48.2% by mass KBr, there would be 48.2g of KBr.
