A 17.3 g sample of an organic compound (a non-electrolyte) was ground up with 50g of camphor to form a homogeneous mixture melting point at 170.0 °C. What is the apparent formula/molecular weight of the organic compound? (Kr of camphor = 37.7 °C/m, melting point of camphor = 178.4 °C) (Note: This is a freezing point depression problem - note the K of camphor - camphor is the solvent.)

a. 1,353 g/mol
b. 1, 285 g/mol
c. 1,573 g/mol
d. 1,185 g/mol​
