Respuesta :
the molarity of KBr solution is 1.556 M
molarity is defined as the number of moles of solute in volume of 1 L solution.
the number of KBr moles in 1 L - 1.556 mol
Therefore in 200.0 L - 1.556 mol/L x 200.0 L = 311.2 mol
Molar mass of KBr - 119 g/mol
mass of Kbr - 311.2 mol x 119 g/mol = 37 033 g
mass of solute therefore is 37.033 kg

What is Molarity?
It is the number of moles of solute in volume of 1 L solution.
Given:
Molarity of KBr solution = 1.556 M
Number of KBr moles in 1 L= 1.556 mol
Calculation for mass:
In 200.0 L = 1.556 mol/L * 200.0 L = 311.2 mol
Molar mass of KBr = 119 g/mol
Mass of KBr = 311.2 mol * 119 g/mol = 37 033 g
Thus, the mass of solute is 37,033 g or 37.033 kg.
