Let's assume that the density of marble is 2.76 gm/cm3. Marble varies somewhat in density depending upon the type of marble; so your marble may vary from this number.
0.75 inch X 1 square foot X 144 square inches/square foot = 108 cubic inches
2.76 gm/cm3 X 16.39 cm3/cubic inch X 108 cubic inches = 4886 gms
0.00220 pounds/gm X 4886 gms = 10.7 pounds
It would weigh about 14.3 pounds .
The answer depends on the material and quality of the carpet.
You cannot weigh an area. Just as you cannot weigh a distance. (How much does one centimeter weigh?)
It depends on the glass type, but for general purposes it is about 19.8 kilograms per square meter
You cannot weigh an area, but you can weigh a volume... so, one cubic meter of stainless steel weighs 7480 - 8000 kg. See related link for the source.
It would weigh about 14.3 pounds .
It depends on the length and width of the plate, and the thickness. A 12 x 12 inch piece of plate aluminum which is 1/2 inch thick has the same length and width as a 12 x 12 inch piece which is 1/4 inch thick, but the 1/2 inch piece will weigh twice as much.

It is not possible to answer the question sensibly. Square feet are a measure of area, whereas weight is a property associated with volume. 10 sq feet of oak would probably weigh less than a feather if it were 1 micron thick. On the other hand, it would weigh a lot if it were 2 foot thick.
The question cannot be answered. A square metre is a measure of area not of volume. A block of lead, with an area of 1 square metre could be a few atoms thick or several metres thick. Their weights will differ considerably.

NBA player Roy Devyn Marble weighs 200 pounds.
the significance of a piece of grass is that they all way .1 of a gram at 3.5cm long.

2 to 3 grams each, somewhere around there. Depends on the size of the marble A marble weighs nearly 4-5 gm.
Granite weighs an average of about 20 pounds per square foot, so a 5' by 8' (40 square feet) piece of granite would weigh approximately 800 pounds.
