Final answer:
The volume of the solution made by dissolving 8.80 g of substance (assumed as Cu(NO3)2) in water to make a 0.240 M solution is 195.4 mL, which is not among the provided options.
Step-by-step explanation:
To calculate the volume of the solution in milliliters, we first need to find out how many moles of CUNO are present in 8.80 g. However, it seems there's an error in the chemical formula provided. Assuming CUNO is a typo and the correct formula is CuNO3, we can proceed. The molar mass of CuNO3 (actually Cu(NO3)2, Copper(II) nitrate) is approximately 187.55 g/mol. The number of moles of Cu(NO3)2 in 8.80 g is:
mols = mass / molar mass = 8.80 g / 187.55 g/mol = 0.0469 mol
Since molarity (M) is defined as moles of solute per liter of solution, we can rearrange the molarity equation to find volume:
Volume = moles of solute / molarity (M) = 0.0469 mol / 0.240 M = 0.1954 L
Now, to convert the volume from liters to milliliters:
Volume in mL = Volume in L x 1000 mL/L = 0.1954 L x 1000 mL/L = 195.4 mL
Hence, none of the given options (a) 37.1 mL, (b) 66.7 mL, (c) 125.0 mL, or (d) 360.0 mL is correct. Therefore, the volume of the solution is 195.4 mL.
