Present estimates (Feb 2009) put the human population at about 6,750,000,000 (6.75 billion).
Most of them (1.3 billion) live in China.
If by 'mass' we mean weight, then we would have to know the average weight of humans in the world. To do this we would have to take into account the fact that (a) mature adults may have an average weight per country, but also that (b) the percentage of children in any given population will differ from that of the population of Another Country, and (c) that childrens' weights increase as they get older.
Any statistical 'average' weight of humans will not take account of the fact that a typical population is comprised of babies, children, youths, mature adults and older persons. Therefore it is doubtful that sufficient records and data are available to compute the actual combined weight/mass of all the humans on the earth at the moment.
What else can I help you with?
How much has the mass of the human population on the earth increased in the weight of the air over year?
The mass of the air surrounding the Earth is approximately 5.15 quadrillion metric tons. While the human population has increased significantly over the years, the mass of the air itself remains relatively constant, with fluctuations primarily due to natural processes. Therefore, the increase in the weight of the air due to the growing human population is negligible and not directly quantifiable in terms of overall air mass. In essence, the human population's growth does not substantially affect the total mass of the Earth's atmosphere.
What is the moon's mass compared to the earth's mass?
1 earth mass = 81.78 moon mass (rounded)1 moon mass = 0.01223 earth mass = 1.223% of earth mass (rounded)The mass of the moon is only 1.2 percent of the mass of Earth.
Is the mass of the moon greater than the mass of the earth?
No. The mass of the moon is a fraction of the earth's mass.
What is the mass of Venus's compared to earth?
The mass on Venus compared to Earth is 80%.
What is the mass of Mars in terms of Earth's mass?
The mass of mars is about 0.107 Earth masses.
How does Uranus' mass differ from Earth's mass?
The mass of Uranus is about 14.5 times the mass of earth.
What is earth's mass as a percent of Jupiter's mass?
Jupiter has a mass that is 317.8x greater than that of Earth. In other words, Earth's mass is equal to about 0.3% the mass of Jupiter.
Is there less mass on Mercury than on Earth?
Yes there is. Its mass is about 5.5% of the earth's mass.
Does the earth and the moon have the same amount of mass?
No, they do not have the same mass. The moon has much less mass than Earth.
Do mars and earth have a similar mass?
No. Mars has about one tenth of Earth's mass. Venus, howevr, does have a similar mass to Earth.
How many Plutos will make the mass of Earth?
Pluto's volume is about 0.6% that of Earth. :)
What is the Earth's mass represented by the Earth's crust?
mass of Earth = 5.97219 × 1024 kilograms. Roughly.The mass of the earth is not represented by the earths crust
