But XOR would say that only one is true. Don't you mean that:

6 is the number of kilograms of some mass of humans
                        AND
400,000,000 is the number of kilograms of some mass of humans
                        AND
"whatever" is the number of kilograms of some mass of humans


Of course, which mass of humans is different for each number, that's why
{loi remna} has to come after the {e}s. The XOR version would say that
only one of those is true, but you want to say that all of them are.

 tu'o

That says the same as the XOR version, but it is a weaker claim than what
you want. You are saying that only one of those three weights is the weight
of some mass of humans. But you want to say that all of those weights are
the weights of some mass (a different mass for each).
