If an insufficient amount of a liquid unknown had been used how would this affect the value of the experimental molar mass?

When the unknown liquid is heated and turned into vapor, the unknown will not occupy the whole container. In the equation to find the molar mass (nRT)/PV, the volume will be greater than the actually volume of the unknown, thus leaving a molar mass that is less than the actual molar mass
