I would double check that data - there is something seriously wrong with it. Are you sure it was water? Are you sure the volume was 10.00 mL? Are you sure about the tare and full weights?
The density of water can be found in any number of handbooks - the CRC Handbook of Chemistry & Physics, or you can just Google for it and a great number of reputable sources are linked.
