Oxygen is a non meta element. Atomic Mass of it is 16.
To determine the molecular formula, you would need the molar mass of the compound. With the molar mass, you can calculate the empirical formula mass and then determine the ratio between the empirical formula mass and the molar mass to find the molecular formula.
The atomic mass of water (H2O) is calculated by adding the atomic masses of its constituent elements, which are hydrogen (H) and oxygen (O). The atomic mass of hydrogen is approximately 1, and the atomic mass of oxygen is approximately 16. Therefore, the atomic mass of water is approximately 18 (1 + 1 + 16).
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
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.
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.
The relative formula mass of lead oxide (PbO) is calculated by adding the atomic masses of the elements in the formula. The atomic mass of lead (Pb) is 207.2 g/mol, and the atomic mass of oxygen (O) is 16.0 g/mol. Therefore, the relative formula mass of lead oxide is 207.2 + 16.0 = 223.2 g/mol.
The relative formula mass of MgCO3 is 84.3 g/mol. This is calculated by adding the atomic masses of magnesium (24.3 g/mol), carbon (12.0 g/mol), and three oxygen atoms (16.0 g/mol each) together.
The relative formula mass of iodine is 253.8 g/mol.
The anhydrous copper sulfate (CuSO4) has a molar mass of 159,62.
The relative formula mass of iron sulfate is 151.85 g/mol. It is calculated by adding the atomic masses of all the elements in the compound, which are iron (Fe), sulfur (S), and oxygen (O).
The relative atomic mass of copper is approximately 63.55. To calculate the relative formula mass of copper, you sum the atomic masses of its atoms, which in this case would just be the atomic mass of copper. Therefore, the relative formula mass of copper would be 63.55.
Oxygen formula O2
The relative formula mass of potassium dichromate (K2Cr2O7) is calculated by adding the atomic masses of its individual elements. The atomic masses of potassium (K), chromium (Cr), and oxygen (O) are 39.1, 52, and 16 respectively. Therefore, the relative formula mass of potassium dichromate is 294.2 g/mol.
The relative formula mass of ethanol (C2H5OH) is 46 g/mol.
The chemical formula is (NO3)-; the mass is 62 g.
The relative formula mass of a hydrogen molecule (H2) is calculated by adding the atomic masses of the two hydrogen atoms. Each hydrogen atom has an atomic mass of approximately 1, so the relative formula mass of a hydrogen molecule is 2.
The formula for it is CaCO3 Therefore it is fairly simple to work out. Ca is 40 C is 12 O is 16 x3 48 Add them all up 100 hope this helps :)
