Please help I have done something wrong as I'm getting a negative for the percent error.

In a laboratory experiment, a student found that a 104-mL aqueous solution containing 2.878 g of a compound had an osmotic pressure of 21.1 mmHg at 298 K. The compound was also found to be nonvolatile and a nonelectrolyte. What is the molar mass of this compound?
