If you mean *exactly* one cup by volume, you have the iceberg scenario. The cup of frozen water will be less dense, so it will weigh less. If you just freeze a cup of water, don't spill any, and *don't* trim the excess to bring the volume back to exactly one cup, then it will weigh exactly what it did at room temp.
In general a fluid ounce of water will be an ounce of weight. A pint of water is 16 ounces which would be one pound.
The same it weighed when it was liquid---but it has a greater volume because ice is "fluffier" than water.
An 18-ounce bucket of water would weigh 18 ounces, which is equivalent to 1.125 pounds.
Assuming that no weight is added or taken away, the weight (or the mass) will remain the same. However, this assumption is not always correct: when you freeze stuff, sometimes it accumulates moisture from the surrounding air, which then freezes.
1 ounce of frozen liquid weighs approximately 0.99 ounces.

Water will stay the same weight when it is frozen, it still has the same molecules that it started with
They weigh the same
Weight of water: 1 imperial fluid ounce = 28.41 grams 1 US fluid ounce = 29.57 grams

An ounce is an ounce.
It both are one ounce then both weigh the same
No, 1 fluid ounce of water does not weigh the same as 1 dry ounce. Water has a density of approximately 1 gram per milliliter, so 1 fluid ounce of water weighs about 1 ounce. Conversely, 1 dry ounce is a measure of weight, equal to 28.35 grams.
No, frozen water weighs the same as liquid water. When water freezes, it expands in volume but maintains the same mass, so the weight remains constant.
1 fluid ounce of water weighs 1 ounce; so they are the same weight if you are talking about water. However, if you are measuring a liquid that has a density greater than that of water, then 1 fluid ounce of that liquid would weigh more than 1 ounce.
