Oxygen is a non meta element. Atomic Mass of it is 16.
What else can I help you with?
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?
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.
What is the atomic mass of water?
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).
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 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 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.
What is the relative formula mass of lead oxide?
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.
What is the relative formula mass for MgCO3?
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.
What is the relative formula mass of iodine?
The relative formula mass of iodine is 253.8 g/mol.
What is copper sulfates relative formula mass?
The anhydrous copper sulfate (CuSO4) has a molar mass of 159,62.
What is the relative formula mass of iron sulphate?
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).
What is the relative formula mass of copper?
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.
What is the formula mass of oxygen?
Oxygen formula O2
What is the relative formula mass of each of the following compounds of potassium dichromate?
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.
What is the relative formula mass of ethanol?
The relative formula mass of ethanol (C2H5OH) is 46 g/mol.
What is the relative formula mass of nitrate?
The chemical formula is (NO3)-; the mass is 62 g.
What are the relative formula masses of hydrogen molecules?
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.
Relative formula mass of calcium carbonate?
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 :)
