There are 4 quarts to a gallon, so that's two gallons of water. One gallon of water weighs about 8 pounds, so two gallons is about 16 pounds.
16.7 lbs, approx
We would also need to know the temperature of the water and amospheric pressure. Think of it this way: Imagine 8 quarts of ice and 8 quarts of steam. They would occupy the same volume (8 quarts) but have drastically different weights.
256 oz. or 16 pounds
Get a scale!!!!!!!!!
Are they US or UK quarts
In US "a pint's a pound the world around"
In Uk "A pint of water's a pound and a quarter"
so that's 16 pounds for US 8 quarts and
20 pounds for the UK measure
water weight 62.4 lb/cuft (density)
62.4 lb/cu ft x1 cuft /7.48gallon x 1 gallon /4 qts = 2.086 lb/qt
8qts x 2.086 lb / qt = 16.68lb
