In one molecule of FeSO4 , there are 6 atoms, which 4 of them are oxigen atoms.
Fe=56,S=32,O=16.been four atoms of oxygen=16*4,which is 64. Molar mass=56+32+64 =152g
120.37 g mol-1

1 mole of iron atoms has the greatest mass - 55,845 g.
1 mole of He-4 isotope weight about 4 g So 1.5 mole of He-4 isotope weight about 6 g
4 grams. Approximately, mass (in grams) of 1 mole of any chemical element is just the atomic mass of this element (4 - for He, 12 - for C, and so on). It follows from the definition of one mole - number of atoms in 12 g of C.
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.
4.3x10^16 atoms He x 1 mole He/6.02x10^23 atoms x 4 g/mole He = answer (do the math)

In this molecule, there are 4 oxygen atoms, so 1 mole of this substance would have 4 moles of oxygen atoms. Each oxygen atom is 16 g/mole, so 64 grams.
16 grams per mole. Methane is CH4. Look at the Periodic table: Carbon is 12 grams/mole and Hydrogen is 1 gram/mole, so 1*12 + 4*1 = 16.
Use the equation Moles(m) = mass(g) / Mr (Relative Molecular Mass). To calculate the Mr , refer to the Periodic Table, for Atomic Masses. For H2SO4 We have H x 2 = 1 x 2 = 2 ( 1 is the atomic mass of H ) S x 1 = 32 x 1 = 32 ( 32 is the atomic mass of S). O x 4 = 16 x 4 = 64 (16 is the atomic mass of O). Adding 2 + 32 + 64 = 98 the Mr of H2SO4 Substituting into the eq'n above 1 mole = mass(g) / 98 Algebraic rearrangement mass(g) = 1 mole X 98(Mr) mass(g) = 98 grams. is the mass of 1 mole of H2SO4 .
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.
PPM is a ratio, unitless: example (micro-litre/litre, or micro-mole/mole...ets) for simplicity the conversion is best understood with a simple example: if we are given the concentration of CO gas ( carbon monoxide) from an engine exhaust. brake power or rated power of the engine should be determined or be given, also mass flow rate of the exhaust gas shoulb be known or calculated: Now the conversion: 1- first determine molar mass of CO=12+16=28 grams/mol 2- determine the molar mass of air appx 29 kg/kmol = 29 g/mole 3- PPM (CO) = 4 (example) thus 4 micro-moles/ 1 mole **equivalent to 4*10^-6 mole / mole 4- { [(4*10^-6 mole/ mole)*( 28/29)* (mass flow)*(3600 sec/1hr)] / power } hope this helps.
The molecular formula of 1-butanol is C4H9OH so the molar mass is: (12)(4)+(1)(9)+(16)(1)+(1)(1)= 74
