What is the molar concentration of 2000. mL of aqueous solution containing 125 g of glucose, C6 H12O6? Molar mass 180.15 g/mol. Report your answer to three significant figures.

M=moles/volumeinLiters=(125/180.15)/2.000

To find the molar concentration of a solution, we need to calculate the number of moles of solute (in this case, glucose) and divide it by the volume of the solution in liters.

Step 1: Calculate the number of moles of glucose:
The molar mass of glucose (C6 H12O6) is 180.15 g/mol. We have 125 g of glucose, so we can calculate the number of moles using the formula:
moles = mass / molar mass
moles = 125 g / 180.15 g/mol

Step 2: Convert the volume of the solution to liters:
We have 2000 mL of solution, so we need to convert it to liters by dividing by 1000:
volume = 2000 mL / 1000 mL/L

Step 3: Calculate the molar concentration:
The molar concentration (also known as molarity) is defined as moles of solute divided by liters of solution:
concentration = moles of solute / volume of solution

Now let's calculate the molar concentration.

moles = 125 g / 180.15 g/mol = 0.693 mol (rounded to three decimal places)
volume = 2000 mL / 1000 mL/L = 2.000 L (rounded to three decimal places)

concentration = 0.693 mol / 2.000 L = 0.347 M (rounded to three significant figures)

Therefore, the molar concentration of the solution is 0.347 M.
