According to the law of conservation of mass if two atoms of hydrogen are used as a reactant how many atoms of hydrogen must be part of the product?
2!
Which part of daltons atomic theory are known to be incorrect?
The idea that atoms are indivisible and indestructible, and the idea that all atoms of the same element have the same mass.
How many Helium-atoms and Carbon-atoms do you have if you have He-atoms with mass of 40amu and C-atoms with mass of 120amu?
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms
What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

Is fusion nuclear decay or nuclear synthesis?
Fusion is nuclear synthesis, combining atoms of lesser mass into atoms of greater mass. Decay is reducing the mass of larger (unstable) atoms to form atoms of lesser mass.
What does adding s neutron to an atoms nucleus do to the atoms mass?
Increases it by one mass unit.
What is the mass in grams of 2x1012 atoms of potassium?
What is the mass, in grams, of 2 × 1012 atoms of potassium?
What is the mass of 4.9810e21 platinum atoms?
The mass of 4.9810e21 platinum atoms is 0,000 042 g.
What has more mass 100 hydrogen atoms 4 sulfur atoms or 1 lanthanum atom?
100 Hydrogen atoms have an atomic mass of 100.794, 4 Sulfur atoms have an atomic mass of 128.26, and 1 Lanthanum atom has an atomic mass of 138.90547.
What is the mass of one mole atoms?
The mass depends on the element whose atoms are concerned. For eg, 1 mol Helium atoms have mass 4 g 1 mol Neon atoms have mass 20 g.
What is the mathematical relationship between atomic mass units and grams?
Tricky bit that, but it's part of the definition of the molar mass. Basically, if you were to collect 6.022×1023 atoms of a substance of a particular atomic mass (lets say 6 for arguments sake), then the resultant pile of atoms would have a mass of 6 grams.
Is it true the size of a mole of atoms has a reasonable mass?
is it true the size of a mmole of atoms has a reasonable mass
