Correct, because if there are fewer protons and neutrons in an atom, it will have a lower mass.
The mass of a calcium atom is around 40 atomic mass units (u), while the mass of a helium atom is around 4 atomic mass units (u). Therefore, the mass of a calcium atom is 10 times greater than the mass of a helium atom.
35.5 grams per mole or 5.90*10^-23 for a single atom
HI, A MOLE IS MOLECULAR MASS. MOLECULAR MASS OF SODIUM IS 23. HENCE, 1.22 MOLE = 1.22*23 = 28.60
32 grams, you can find the mass of one mole of any element by looking at its atomic mass eg chlorine has Atomic mass of 35.5 so the mass of one mole of chlorine is 35.5 grams.
10.81g This is found by looking at the atomic weight. The atomic weight refers to the mass of a singe atom in units of AMU (atomic mass units) and it also refers to the mass of one mole of the element in grams.
If the Atomic Mass of an atom is x, then the mass of 1 mole of the atoms is x gram.
For the same reason that one dozen pencils has a smaller mass than one dozen bricks. Each atom of carbon weighs less than each atom of sulfur, and a mole of each has the same number of atoms, so a mole S will weigh more than a mole C.

The mass of a calcium atom is around 40 atomic mass units (u), while the mass of a helium atom is around 4 atomic mass units (u). Therefore, the mass of a calcium atom is 10 times greater than the mass of a helium atom.
mass of one mole of oxygen atom is 16 grams. atomic weight of any atom is equal to mass of 1 mol of that atom...
To calculate the weight of a mole of an atom in grams (molar mass), you add up the atomic masses of all the atoms in one mole of the substance. This can be found on the periodic table and is usually given in atomic mass units (amu). The molar mass is expressed in grams per mole.

35.5 grams per mole or 5.90*10^-23 for a single atom
No, one atom is not equivalent to one gram. Atoms are incredibly small units of matter, while grams are a unit of mass. The mass of an atom is typically measured in atomic mass units (amu) or grams per mole.
1 mole of H weights 1.008 g 1 mole = 6.02 x 10^23 particles Mass of 1 atom = 1.008 g / 6.02 x 10^23 = 1.67 x 10^-24 g
HI, A MOLE IS MOLECULAR MASS. MOLECULAR MASS OF SODIUM IS 23. HENCE, 1.22 MOLE = 1.22*23 = 28.60
molar mass is just the moleular mass of an atom or molecule.
