Question

What is molarity of propanol, C3H7OH, when 60. mL propanol is mixed with enough H2O to make a final volume of 100. mL?

The MW of propanol = 60.11 g/mol and the density of propanol = 0.804 g/mL.

Answer 1

g propanol = volume x density
mols propanol = grams/molar mass
M propanol = mols/L solution. which is 0.100 L.

Answer 2

Thanks!
