What it means
も follows a quantity phrase to emphasize that the amount is surprisingly large or greater than expected. It can mean “as many as” with countable items and “as much as” with amounts or uncountable things. The quantity usually feels notable from the speaker’s point of view.
Usage note
This use of も is different from its common meaning “also.” It attaches directly after the number-and-counter phrase, such as 十個も. The sentence ending, not も itself, shows whether the sentence is familiar or polite.
