Mass is a constant everywhere in the universe. The weight on the moon is about one sixth of the weight on the earth, because the mass of the moon is about one sixth of the mass of the earth reducing the force of gravity.
Yes, the Moon has about 1/81 of the Earth's mass.
The source of gravity on the Moon is its mass. Gravity is a force that attracts objects with mass towards one another, and the amount of gravity depends on the mass of an object. The Moon's gravity is about 1/6th of Earth's gravity due to its smaller mass.
Mainly because the moon has only about 1/80 as much mass as Earth has. True, the moon is considerably smaller than the Earth, allowing you to get closer to its center of mass. But not close enough to compensate entirely for the difference in mass.
Modern thought has it that a body about the size of Mars, and given the name of Theia, collided gently with the Earth, and the debris from the collision resulted in the formation of the Moon.Thus much of its rocks are similar to those of Earth, but it is mineral deficient. Earth's core was likely not involved in the collision.The Moon obviously has an uneven distribution of mass, and that is why the Moon presents one face to Earth all the time. It probably had significant spin at some time, but tidal drag with the Earth has canceled this out.1 earth mass = 81.78 moon mass (rounded)1 moon mass = 0.01223 earth mass = 1.223% of earth mass (rounded)
the mass of one litter of water is 1g and the mass does not change due to different gravity.
1 mole H2O = 18.015g H2O = 6.022 x 1023 molecules H2O 1.5 x 1023 molecules H2O x 18.015g H2O/6.022 x 1023 molecules H2O = 4.5g H2O
The moon that is described as having the largest mass is Ganymede. This is one of the moons of Jupiter. Its mass is about 2.02 times that of Earth's moon.
Mass is a constant everywhere in the universe. The weight on the moon is about one sixth of the weight on the earth, because the mass of the moon is about one sixth of the mass of the earth reducing the force of gravity.
Mass
It is matter. because H2O means water, and water is one form of matter cause its liquid.
Exactly 1 kilogram
The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17 The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18 This means that one mole of NH3 weigh less than one mole of H2O
For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. H2O=18.0 grams235 grams H2O / (18.0 grams) = 13.1 moles H2O
The molar mass of water is approximately 18 grams/mol. So, one water molecule has a mass of 18/6.022 x 10^23 grams. Therefore, the mass of 1.5 x 10^23 water molecules would be 18 x 1.5 x 10^23/6.022 x 10^23 grams.
one mole of any element is equals to its gam(Gram Atomic Mass) and one mole of any molecule is also equals to that molecules gram atomic mass. Lets calculate the gram molecular mass of water : h2o = 2 hydrogen atoms, 1 oxygen atom = 2 hydrogen x 1g (gram atomic mass of hydrogen) + 1 oxygen x 16g (gram atomic mass of oxygen) = 2 + 16 = 18g Therefore 1 mole of water contains 18grams.
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. Therefore, for the products NaCl and H2O to be formed, the reactants must contain the same amount of sodium, chlorine, and hydrogen atoms as found in NaCl and H2O, respectively.
