- Hope that helped! Please let me know if you need further explanation.
Volume of solution in liters:
5.00 x 10² mL / 1000 => 0.5 L
number of moles:
mass of solute / molar mass
21.1 / 119.0 => 0.1773 moles
Molarity = number of moles / volume
M = 0.1773 / 0.5
M = 0.355 mol/L

Answer:
Explanation:
Molar mass of NaCl = 58.44 g/mol
Mass of NaCl = 195 g
Volume of solution = 4.05 L
Molarity of solution is
The molarity of the solution is
Moles of NaCl = 4.63 mol
Volume is given by
The volume of the solution that contains the required amount NaCl is
Volume of solution =
Moles of solution is given by
The number of moles of NaCl is .
