mols solute/kg solvent = molality
You know molality, you know kg solvent, calculate mols solute.
Then mols = grams/molar mass.
You know mols from above, you know molar mass solute, calculate grams solute.
What mass (g) of the solute C3H8O3 should be mixed with 8270 mL of the solvent H2O to produce a solution that is 1.02 m glycerol.
Molar Mass (g/mol)
C3H8O3 92.09
H2O 18.015
Density (kg/L):
C3H8O3 1.261
H2O 0.9982
Name/Formula:
glycerol
C3H8O3
water
H2O
