What is the molarity of A solution containing 9.478 Grams of RuCl3 in enough water To make 1.00 L of solution.

1 answer

To find the molarity of the solution, we need to first calculate the number of moles of RuCl3 present in 9.478 grams.

The molar mass of RuCl3 is 207.2 + (3 x 35.5) = 241.7 g/mol.

Number of moles = (Mass of compound)/(Molar mass of compound)
Number of moles of RuCl3 = 9.478 g / 241.7 g/mol = 0.0392 mol

Now we can calculate the molarity using the formula:

Molarity = (Number of moles of solute) / (Volume of solution in liters)

Molarity = 0.0392 mol / 1.00 L = 0.0392 M

Therefore, the molarity of the solution is 0.0392 M.
