Obviously one pound of water weighs exactly the same as one pound of ice... but I doubt that was the intent of the question.
When water freezes it expands rapidly adding about 9 % by volume. Fresh water has a maximum density at around 4° Celsius. Water is the only substance where the maximum density does not occur when solidified. As ice is lighter than water, it floats.
By "lighter" they obviously mean less dense. The page also has a table of the density of liquid water at various temperatures. (I think it unlikely it is "the only substance" with this property - there are many things we have not seen or tested...)
The feedback that says H2O weighs the same at any temperature is true if you keep the same number of water molecules, but the density changes. This has been known for many years and is well documented. Floating ice may or may not have air bubbles, but it does not need them to float.

It's kind of a vague question, so let me explain my answer:
Ice floats in water because it is less dense than liquid water. However, because of its structure, when ice melts, it takes up just about the same amount of space as when it was solid.

as long as there is the same amount of water and ice, they weigh the same. ice is just another form of water

Water weighs more

They're equal. One pound of ice weighs the same as one pound of water.

If you had the same quantity of each, water would weigh more

It would depend on the quantity, but Ice is less dense then water, hence it floats

I would imagine that they weigh the same depending on the sample size.

They weigh the same.
