The mass of the earth has been calculated as 6 x 10^24 kilograms. (Mass is a little different than weight, but let's not get into that.) Here's a link on how this calculation was done.

5.9742x10^24 kg which is nice
and I will tell you the calculation to work it out. and take you through it what more could you possibly wont.
F=-G(m1m2)/r^2 and you will need F=ma
F= force between
G= gravitional constant of 6.67x10-11
m1 = mass of earth (we dont know)
m2= mass of 200kg object falling towards earth
r^2= square of the radius of the earth as diametre =12756000m
a= acceleration due to gravity 9.81ms-2
ma=m1m2=(Fr^2)/-G
m2 including F/m2 = a
ar^2/-G=m2
9.81x(12756000/2)^2 / -6.67x10-11 = 5.98x10^24kg woooo
except that kgs is not a weight its a mass and they are different , weight is measured in newtons N i suppose it mite be 5.98x10^24x9.81 weight is a force so it is F=ma however the acceleration is not always 9.81ms_2 it depends on the distnace from the centre in fact for a force to exist there need to be an interaction between two bodies, but i dont want ot answer that question i hope the first bit is enough.

The Volume of Earth is 1.083 207 3Ã1012 km³.

the earth does have a weight because it is attracted to the sun by the gravitational pull, that is why it orbits the sun.
it would be hard to say how much it weighs but it would be 10x its mass and the unit would be in newtons

The current best estimate is: 5.9725 billion trillion metric tons, or 5.9725 x 10^24 kilograms, or 1.3167109 x 10^25 pounds (13,167,109,000,000,000,000,000 pounds). Suffice to say, that's a lot of mass.

The right way of asking this is how much mass does the earth have... and the answer is 5.96 Ã 1024 kg.

It would be more proper to ask, "What is the mass of planet Earth?"1 The quick answer to that is: approximately 6,000,000,000,000,000,000,000,000 (6E+24) kilograms.
