It depends how small it is crushed and how tightly it's packed. The smaller it's crushed and more tightly it's packed, the heavier it is as there is more ice and less space between the pieces of ice. In the most finely crushed and firmly packed volumes of the frozen stuff, the cubic foot of crushed ice will approach being a solid block. A cubic foot of water weighs about 62.4 pounds. A solid block of ice of the same volume weighs about 57.5 pounds. A cubic foot of "normal" crushed ice might weigh 35 to 45 pound range. And it could weigh more or less.
A cubic yard of crushed lava rock typically weighs around 2,750 pounds (1.375 tons).
On average, 1 cubic foot of topsoil can weigh around 75-100 pounds, so 75 cubic feet of topsoil would weigh approximately 5,625-7,500 pounds. The weight can vary based on moisture content and composition of the soil.
Snow is not uniform for density so you would have to weigh the cubic foot you are interested in. Each pound or kilogram would be composed of 1/9 hydrogen and 8/9 oxygen (by mass) since the molecular weight of water is 18, the atomic weight of hydrogen is 1 and the atomic weight of oxygen is 16. Based on 1 cubic foot of snow being about 10% the weight of a cubic foot of water, it would weigh approximately 6.25 pounds and contain about 5.56 pounds of oxygen.
The answer depends on the density of the rock. A cubic foot of pumice, for example, can have a mass of around 15.6 pounds whereas minerals rich in metals such as iridium will have mass exceeding 1200 pounds.
1 cubic yard is 27 cubic feet, so 3 cubic yards is 81 cubic feet. At 125 lb per cubic foot, that much topsoil would weigh 10,125 lb. At 2000 lb per ton, that converts to 5.0625 tons (if we assume complete precision of all the numbers - if not, then we would be limited to 1 digit of precision because the 3 in 3 cubic yards is only precise to 1 digit. In that case we would have to round the answer off to be 5 tons)
A cubic yard of finely crushed asphalt will weigh about 2,600 pounds
Pulverised coal = 38 pounds per cubic foot
450
It would weigh 1,342 pounds.
A cubic yard of crushed lava rock typically weighs around 2,750 pounds (1.375 tons).
9.052 pounds
That depends on how much of it you have!One pebble doesn't weigh very much, but a cubic foot of granite weighs 168 pounds! Compare that to water, which weighs about 62 pounds per cubic foot.
The weight of one square yard of crushed seashells will depend on the thickness and density of the crushed shells. On average, crushed seashells weigh around 1,500 to 2,000 pounds per cubic yard, so you can use this range to estimate the weight of one square yard based on the thickness of the layer.

It depends what the ash comes from.
Redwood weighs around 28 to 31 pounds per cubic foot, making it a relatively lightweight wood compared to others, which can weigh significantly more per cubic foot.
1 cubic foot = 28.316847 litres The answer is in volume, the question was asking for weight. Thanks
