It's impossible to say how many stones are in 141 without more context. "141" could refer to:

* A number: 141 is just a number, not a measure of stones.

* A measurement: It could be 141 of something, like 141 feet, 141 grams, or 141 cubic meters. We need to know what unit of measurement "141" represents.

To help me give you a proper answer, please tell me:

* What is "141" referring to? (e.g., 141 stones, 141 pounds of stones, etc.)

* What type of stones are we talking about? (e.g., small pebbles, large boulders, etc.)

Once I have that information, I can help you estimate the number of stones!
