The mass of Ceres is 9.43 * 1020 kg or 0.0158% of the Earth's mass.
Ceres (designated as 1 Ceres) has an average diameter of about 950 km (590 miles). It is by far the largest object in the asteroid belt. It is, however, the smallest dwarf planet. By comparison, Pluto has a diameter of about 2300 km (1430 miles).The asteroid is slightly oblate, but apparently not because of rotation. Its polar diameter is only about 909 km (565 mi) while its equatorial diameter is about 975 km (606 mi). NASA lists the "average" diameter as 930 km (580 mi).
(The total mass the asteroid belt is lighter than the moon. The total mass the asteroid belt is lighter than the moon.) However; If the total mass of the asteroid belt were reconstituted, it would altogether be less than half of the mass of the moon. But if we consider that if the hot molten interior of a hypothesized planet that might have been the asteroid belt was under great pressure and heat, as are all of the known planets, we could then hypothesize that approximately 90+% of the mass of said hypothesized planet would have been expanded by a factor of at least 1600:1. Possibly more if the interior was superheated. That figure is only if the matter of the interior had the matter weight and density of water. If it were denser, having the same density of magma, then the rate of expansion would be much greater. Possibly as much as 12000:1. So if you take this into consideration, then the asteroid belt could indeed have had a total mass great enough to compete with one of the terrestrial planets
Heaviness, weight, is variable, depending upon--among other things--the mass at the bottom of the gravity well.It would be more accurate to ask regarding the mass of asteroids, but that is equally unanswerable. Asteroids vary in size from microscopic to minor planetoids.

One of the largest asteroids, Ceres was discovered in 1801. With its estimated average radius of about 461 km, and its estimated mass of 9.43 x 1020 kg (0.00015 of Earth's mass, 0.0128 of the Moon's mass), the acceleration of gravity on its surface is estimated at 0.27 m/s2, or 2.8% of its value on the Earth's surface. If you weigh 150 pounds on Earth, you'll weigh about 4pounds 2.1ounces on Ceres.
The mass of Ceres is 9.43 * 1020 kg or 0.0158% of the Earth's mass.
My gosh this is exactly the same question as one of my HW questions! But anyway here: Ceres: 9.43 * 1020 kg Pallas: 2.11 x 1020 kg
About 2 x 1020 kg.

3% of 1020 = 3% * 1020 = 0.03 * 1020 = 30.6
It is: 1020
1020-1029kilogram per cubic metre- the standard variance for surface sea water.
3% of 1020= 3% * 1020= 0.03 * 1020= 30.6
