Oxygen is a non meta element. Atomic Mass of it is 16.
To calculate the relative formula mass of sulfur dioxide (SO₂), you need to sum the atomic masses of its constituent elements. Sulfur (S) has an atomic mass of approximately 32.07 g/mol, and oxygen (O) has an atomic mass of about 16.00 g/mol. Since SO₂ contains one sulfur atom and two oxygen atoms, the calculation is: 32.07 + (2 × 16.00) = 32.07 + 32.00 = 64.07 g/mol. Therefore, the relative formula mass of SO₂ is approximately 64.07 g/mol.
To calculate the relative atomic mass of oxygen, you multiply the mass of each isotope by its natural abundance (in decimal form), and then sum these values. The calculation is as follows: [ \text{Relative atomic mass} = (16 \times 0.990) + (17 \times 0.0004) + (18 \times 0.0020) = 15.84 + 0.0068 + 0.036 = 15.8868 ] Thus, the relative atomic mass of oxygen is approximately 15.88 amu.
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
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.
To calculate the relative formula mass of sulfur dioxide (SO₂), you need to sum the atomic masses of its constituent elements. Sulfur (S) has an atomic mass of approximately 32.07 g/mol, and oxygen (O) has an atomic mass of about 16.00 g/mol. Since SO₂ contains one sulfur atom and two oxygen atoms, the calculation is: 32.07 + (2 × 16.00) = 32.07 + 32.00 = 64.07 g/mol. Therefore, the relative formula mass of SO₂ is approximately 64.07 g/mol.
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 Mg(OH)2 can be calculated by adding the atomic masses of all the elements in the compound. The atomic mass of magnesium (Mg) is 24.305 amu, oxygen (O) is 15.999 amu, and hydrogen (H) is 1.008 amu. Therefore, the relative formula mass of Mg(OH)2 is calculated as follows: Mg = 24.305 amu, O = 15.999 amu x 2 = 31.998 amu, H = 1.008 amu x 2 = 2.016 amu. Adding these values together gives a total relative formula mass of Mg(OH)2 as 24.305 + 31.998 + 2.016 = 58.319 amu.
