Concentration Calculations
A chemist combines 30 mL of water with 15 mL of methanol. What are the volumetric, weight,
and molar concentrations of each component in the solution? Density of water = 1 g/mL;
Density of methanol = 0.79 g/mL)
Concentration:
Volume of water =
Volume of methanol =
Total volume of solution =
