What is the atomic mass of water?
The relative atomic mass of hydrogen is 1 and for oxygen it's 16. This gives water (which has the formula H2O) a molecular mass of 18.
What is the mass of oxygen present in 20g of sulfur trioxide in this equation?
The molecular formula of sulphur trioxide is SO3. What is the mass of oxygen present in 20 g of sulphur trioxide? (Relative atomic mass: S = 32; O = 16) need help
What is the formula for ozone?
The formula weight for O3 is the same as the molecular weight which is taking all the elements, multiplying its mass, and then adding the products. Oxygen's mass is 16 g on the periodic table & there's three of them so: 16x3= 48 g (molecular weight) = This is your Formula weight. Hope that helped.
A compound has a mass of 16.7g 12.7g Iodine 4g Oxygen Therefore the empirical formula is I2O5 What additional information do you need to work out the molecular formula?
You need to know the Relative Molecular Mass of the compound, then you find the ratio of that compared to the R.M.M. of I2O5 and then multiply the ratio by I2O5. That should be it.
What is the molecular formula of relative mass of 72?
There are many compounds with a relative mass of 72.Eg. pentane (C5H12), methyl butane (CH3)-(C4H9), dimethyl propane (CH3)2-(C3H6). Inorganic formula's can not easily be guessed, but undoubtly be found.Only one (isotope of an) element has the relative mass of 72: Gallium, (Ga-72), but this is not a natural, stable isotope. Gallium has not a molecular formula (being a metal like aluminum) only an atomic symbol: Ga.
What is the relative formula mass for MgCO3?
relative formula mass of MgCO3
What is the atomic mass of water?
The relative atomic mass of hydrogen is 1 and for oxygen it's 16. This gives water (which has the formula H2O) a molecular mass of 18.
What is the formula mass of oxygen?
Oxygen formula O2
What is the mass of oxygen present in 20g of sulfur trioxide in this equation?
The molecular formula of sulphur trioxide is SO3. What is the mass of oxygen present in 20 g of sulphur trioxide? (Relative atomic mass: S = 32; O = 16) need help
What is the formula mass for zinc nitrate?
Relative atomic mass: Zinc= 65 Nitrogen= 14 Oxygen= 16 Nitrate= nitrogen and oxygen= 30 Formula for zinc nitrate: Zn(NO3)2 NO= 30 NO3= 90 Zn= 65 Zn(NO3) x2 = Zn(NO3)2= 310 Formula mass (molecular mass)(Mr) of zinc nitrate = 310
What is the formula mass of hydrogen?
The relative formula mass of a molecule of hydrgoen is two (2 x 1).
What is the Calculation of relative formula mass of Mg(OH)2.?
Add the atomic masses of each element present. It would be atomic mass of Mg + 2x atomic mass of oxygen + 2x atomic mass of hydrogen.
What is the relative formula mass of iron sulphate?
55
What is the relative formula mass of ethanol?
46.068g
The average relative mass of an ozone molecule is 48.0 you. An ozone molecule contains only oxygen atoms. What does this molecular weight indicate about the formula of the ozone molecule?
The ozone molecule (O3) has 3 oxygen atoms.
What is the formula of a molecule of oxygen?
The formula of an oxygen molecule is O2 (2 is a subscript but now WA doesn't permit to write a subscript).15.9994 g/mol is the molecular mass of oxygen. Formula mass is a sum of atomic mass of atoms in the molecule. In O2 there are two oxygen so it will be about 32g/mol
What is the relative formula mass of nitrate?
The chemical formula is (NO3)-; the mass is 62 g.
