Answer:
1.06M
Explanation:
Given parameters:
Mass of HBr = 50g
Volume of water = 600mL
unknown:
Molarity of the solution = ?
Solution:
The molarity of a substance is the number of moles of solute in a volume of solution.
Mathematically;
Molarity = [tex]\frac{number of moles }{volume}[/tex]
Since the number of moles is unknown, let us solve for it;
Number of moles = [tex]\frac{mass}{molar mass}[/tex]
Molar mass of HBr = 1 + 80 = 81g/mol
Number of moles = [tex]\frac{50}{81}[/tex] = 0.64mole
Convert the volume to liters or dm³; 600mL = 0.6L or 0.6 dm³
Input the parameters and solve;
Molarity = [tex]\frac{0.64}{0.6}[/tex] = 1.06M
