How many sugar molecules are in a 3 m sugar solution (v=1l)?

about 1.8x10^24 sugar molecules. Since we have 1 liter of a 3 Molar solution of sugar, we have 3 moles of sugar molecules. To convert from moles to molecules, just multiply by Avogadro's number which is 6.0221409x10^23. So 3 * 6.0221409x10^23 = 1.80664227x10^24 Rounding to 2 significant figures gives 1.8x10^24 molecules.
