The mass of solute required to produce 537.6 mL of a 0.243 M solution of KBr is 15.6g.
How to calculate mass?
The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass.
However, according to this question, the number of moles needed to produce 537.6 mL of a 0.243 M solution of KBr must be calculated as follows:
0.243 = n/0.5376
n = 0.243 × 0.5376
n = 0.1306mol
Molar mass of KBr = 119g/mol
mass of KBr = 0.1306 × 119
mass of KBr = 15.6g
Therefore, the mass of solute required to produce 537.6 mL of a 0.243 M solution of KBr is 15.6g.
