Answer:
30 moles of ethanol are needed to prepare a 25 m solution, using 1200 g of water
Explanation:
This a short problem of solutions:
Our solute is ethanol: C₂H₅OH
Our solvent is water-
25 m, is our solution's concentration. m means molality (moles of solute contained in 1kg of solvent).
Our solvent mass is 1200g. We convert them to kg
1200 g . 1kg / 1000g = 1.2 kg
m = mol/kg → mol = m . kg
mol = 25 mol/kg . 1.2kg →30 moles
