Mass is the amount of matter (material) that makes up an
object.Weight is defined as the product of a body's mass and the gravitational acceleration in which the mass is located.(Weight = Mass x Gravity)Weight is actually the measure of gravity pulling on you. On Earth, the
Earth pulls on you, and you pull on it. The amount of gravity is determined by the size of the two objects pulling on each other. The moon is about 1/6 as big as the Earth. So it pulls on you with about 1/6 the force. So if you could go to the moon, you would weigh about 1/6 of what you weigh on
Earth. Let's say we have a 1kg object (a kilogram (kg) is a
measure of mass). The value of gravitational acceleration
on Earth = 9.8m/s^2. On the moon, gravitation acceleration
is 1.67 m/sec^2. So how much does that object weight on
the Earth verses the Moon?
Earth
1kg X 9.8m/s^2 = 9.8 Newtons
Moon
1kg X 1.67m/s^2 = 1.67 Newtons

What you have asked for the weight of the moon but in fact you want to know the mass of the moon which is 7.36*10^22 kg (or 73,600,000,000,000,000,000,000 kilograms assuming I got enough zeros in there and not too many).

Weight of the moon is about 81 billion tons.
Sir Isaac Newton calculated that the gravitational force between objects
(say planets, or anything else) is proportional to the square of the
masses, and inversely proportional to the square of the distance between
them. Cavendish measured the constant of proportionality. It is known as
follows:
f = GMm/r^2
By using a body's mass, knowing the force (mg) and the radius of the earth,
the mass of the earth can be calculated.
Now, knowing the mass of the earth, and the orbital radius of the moon, and
the acceleration of the moon about the earth, the mass of the moon can be
found.

That depends. If you are talking about the Earth's moon, then its mass is 7.35 x 10E+22 Kg (73.5 sextillion Kilograms or 161.7 sextillion pounds).
But there are a lot of other moons in the solar system.

Moon factfile :
Distance from earth is 384,000 km (238,600 miles)
Diameter : 3,476 km
Orbit time : 27 earth days, 7 hours
Dont know about the weight

the moon is in space no gravity so it weights nothing
but u cant pick it up hahah

My Physics book says 7.35 E 22kg.
Which means 73,500,000,000,000,000,000,000 kg

If it weights as much as two cookies, or weights as much as 400 buses, what difference does that make in your life?
