Answer :
the molarity of a solution formed by dissolving 97.7 g libr in enough water to yield 1500.0 ml of solution is 0.372 M
To calculate the molarity of a solution, you need to know the number of moles of solute (in this case, libr) in the solution and the volume of the solution in liters.
First, let's convert the mass of libr from grams to moles:
97.7 g libr / (its molar mass in g/mol) = moles of libr
The molar mass of libr can be found in the periodic table and it is 175.21 g/mol. So:
97.7 g / 175.21 g/mol = 0.558 mol
Next, let's convert the volume of the solution from milliliters to liters:
1500.0 ml x (1 L/1000 ml) = 1.5 L
Finally, we can calculate the molarity of the solution:
0.558 mol / 1.5 L = 0.372 M.
