It depends on the molecule. Carbon dioxide has a molecular mass of about 44 AMU, but most other molecules do not.
2 moles H2SO4 (98.086 grams/1 mole H2SO4)= 196.172 grams of sulfuric acid====================

C6H12O3 is a molecular formula that contains 54.5% C, 9.1% H, and 36.4% O and has molar mass of 132 amu.

The relative atomic masses of sulfur, oxygen and hydrogen are 32, 16 and 1 respectively. The molecular formula of sulfuric acid is H2SO4. Therefore, sulfuric acid has a mass number of 98 g/mol.

To calculate the molecular mass of P3S4, we need to determine the atomic masses of phosphorus (P) and sulfur (S). The atomic mass of phosphorus is 30.97 amu, and the atomic mass of sulfur is 32.07 amu. Since there are three phosphorus atoms and four sulfur atoms in P3S4, we multiply the atomic masses and add them together: (3 x 30.97) + (4 x 32.07) = 327.74 amu. Therefore, the molecular mass of P3S4 is 327.74 amu.

This is impossible. In order to find this you must know the elements in the compound
There are three oxygen atoms in an ozone molecule. The RAM of oxygen is 16. Therefore the molecular mass of ozone is 16x3=48u.
The density of a gas is proportional to its molecular mass. Nitrogen (N2) contains 2 nitrogen atoms each with a mass of about 14 AMU (atomic mass units) for a total molecular mass of about 44. Carbon dioxide (CO2) contains 2 atoms of oxygen, each with a mass of about 16 AMU and 1 carbon atom with a mass of about 12 AMU for a total mass of 44.
The only difference is the name of the unit; the numerical values are the same. However, the value in amu is the mass of a single molecule, while the molecular weight in grams is the mass of Avogadro's number of molecules. The mass of Avogadro's number of molecules is called a Gram-mole. The molecular weight of , say, Hydrogen H2 is 2 amu. A gram mole of this would be 2 grams. The molecular weight in grams is the weight of this molecule in real grams and is an extremely small value.
