Final answer:

The molarity of the solution is 0.269 M.

Step-by-step explanation:

To find the molarity of a solution, we use the formula:

Molarity (M) = moles of solute / volume of solution (in liters)

In this case, we need to convert the mass of the solute (29.0 g) to moles by dividing by its molar mass (337 g/mol). Then, we convert the volume of the solution (330 mL) to liters by dividing by 1000. Finally, we divide the moles of solute by the volume of solution to find the molarity.

Molarity = (29.0 g / 337 g/mol) / (330 mL / 1000 mL/L)

Molarity = 0.269 M

Molarity is a measure of the concentration of a solute in a solution, expressed as the number of moles of the solute per liter of the solution. It's denoted by the symbol "M" and is calculated using the formula:

Molarity (M)

=

Number of moles of solute

Volume of solution in liters

Molarity (M)=

Volume of solution in liters

Number of moles of solute

For example, if you dissolve 2 moles of a substance in 1 liter of solution, the molarity would be 2M

2M (2 moles / 1 liter). It's a fundamental concept in chemistry, commonly used in various calculations involving solutions and reactions.
