If the MgSO4 is the only oxygen containing compound in the salt, there must be four moles of oxygen atoms, and the number of atoms in 4 moles is 4 multiplied by Avogadro's number or about 2.409 X 1024 atoms.
1 molecule of MgSO4 has 4 oxygen.
1 mole of MgSO4 molecule has 6.023 x 1023 molecules or 4 x 6.023 x 1023 atoms of oxygen
So. 1.04 mole of MgSO4 molecule will have 1.04 x 4 x 6.023 x 1023 atoms of oxygen or 25.06 x 1023 atoms of oxygen
There are no oxygen atoms in a molecule of table salt. Table salt is sodium and chlorine.
120,37 g for the anhydros salt.

Gold, as it has the higher molar mass.
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ratio of isotopes equal to that in nature - has a mass of 12.0107 grams.

2 NaOH + MgSO4-----Mg(OH)2+Na2SO4 1 MOLE OF MgSO4 produce one mole of Mg(OH)2 SO 1 MWT OF MgSO4 PRODUCE1MWT OF Mg(OH)2 HENCE 120 GM MgSO4 PRODUCE 58 gm OF Mg(OH)2 and so on if x gm of MgSO4 PRODUCE y gm OF Mg(OH)2 x=(120*y)/58 ---- ----
Do you mean from this reaction? MgSO4 + 2H2O -> Mg(OH)2 + H2SO4 let us assume water is in excess 0.01246 MgSO4 (1 mole Mg(OH)2/1 mole MgSO4) = 0.01246 moles Mg(OH)2 produced ----------------------------------------------- This reaction is one to one.

Gold, as it has the higher molar mass.
No Magnesium Sulfate (MgSO4) has a mass of 121, and Sodium Chloride (NaCl) has a mass of 59.
This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)
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.
