The weight of a mouse is typically an average of 12 to 30 g.

It's about one-tenth as heavy as a liter of Water.
In other words, 115 grams is 0.11499680 times the weight of a liter of Water, and the weight of a liter of Water is 8.6958940 times that amount.(fresh; 4° C / 39.2° F; maximum density)
Contrary to popular belief, 1 liter (0.0.264172052358148 gal) of water at 4° C / 39.2° F (its point of maximum density) weighs 1,000.028 grams rather than 1 kg exactly. The total volume of water on the planet Earth is about 13,590,000,000,000,000,000 (13.59 quntillion) L (3,590,000,000,000,000,000 gallons).
