Answer:
Explanation:
To calculate the weight of your coffee mug when it's filled with water, you need to consider the weight of the water added to the weight of the empty mug.
The empty mug weighs 200 grams.
To find the weight of the water, you need to convert the volume (260 cm^3) to grams, assuming that 1 cm^3 of water weighs 1 gram (which is true for water under typical conditions).
So, the weight of the water is 260 grams.
Now, add the weight of the empty mug to the weight of the water:
Weight of mug + Weight of water = 200 grams + 260 grams = 460 grams
Therefore, when you fill your coffee mug with water, it will weigh 460 grams.
