The mass of the precipitates would be larger

Since, we know that when the precipitates are taken out for quantification, they may contain a lot of impurities attached to them like ions or different compounds.

So, when the precipitates are washed with water, most of the impurities are dissolved in water and get washed away with it. After then, the precipitates are dried to remove the excess amount of water to avoid its contribution in the final mass.

Therefore, if we do not wash the precipitates with water before drying it, there are chances that the impurities are still attached to them. This will add to the mass of the precipitates.

So, the mass of the precipitates would be larger.
