Answer: The instrument weigh 204 ounces on Earth.
Explanation:
Since we have given that
Instrument weighed on the moon = 34 pounds
As we know that
The force of gravity on Earth is 6 times greater than on the moon.
So, the weight of instrument on the earth is 6 times the weight on the moon.
Mathematically, it is expressed as

Hence, the instrument weigh 204 ounces on Earth.
