Question

What volume ( L ) of the solute HCO2H should be combined with 5480 mL of the solvent H2O to make a solution that is 0.443 m HCO2H.

Answer 1

molality = moles/kg solvent

0.443 m = moles/5.48 kg
Solve for mols HCOOH.
moles HCOOH = grams/molar mass
Solve for grams.
grams(mass) = volume x density.
You have mass, look up density, calculate volume HCOOH.
