What is the empirical formula for a compound that is 31.9\% potassium 28.9\% chlorine and 39.2\% oxygen?

The empirical formula is KClO3 , potassium chlorate.

How do you find the empirical formula of a compound with molar mass?

Calculate the empirical formula molar mass (EFM). Divide the molar mass of the compound by the empirical formula molar mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2.

What is the empirical formula GCSE?

Empirical formulae The empirical formula of a compound is the simplest whole number ratio of atoms of each element in the compound. It is determined using data from experiments and therefore empirical. For example, the molecular formula of glucose is C 6H 12O 6 but the empirical formula is CH 2O.

What is the total mass of hydrogen in each of the molecules a CH4?

Methane (CH4) has a molar mass of 16g/mol . So, 32g of methane will be 2 moles of it. Know that, hydrogen has a molar mass of around 1g/mol . In methane, there are four hydrogen atoms, so the total mass of hydrogen is 4g/mol in methane, which is 14 of the mass of methane.

What is the molecular formula if the empirical formula is C2H5?

butane
The simplest formula for butane is C2H5 and its molecular mass is about 60.

What is the empirical formula for phosphorus and oxygen in P2O5?

The empirical formula for a compound that is 43.6\% phosphorus and 56.4\% oxygen is P2O5. In the formula, the P stands for phosphorus and the O standards for oxygen, so there are 2 phosphorus (P) atoms and 5 oxygen (O) atoms in the compound. The atomic mass of phosphorus (P) is 30.974 u and the atomic mass of oxygen (O) is 15.999 u.

What is the formula for phosphorus in 100g of stuff?

In 100 ⋅ g of stuff there are 43.64 ⋅ g phosphorus and 56.36 ⋅ g oxygen. We divide thru by the ATOMIC masses of each constituent: P: 43.64 ⋅ g 31.00 ⋅ g ⋅ mol−1 = 1.41 ⋅ mol phosphorus. We divide thru by the SMALLEST molar quantity, we want to get whole numbers: A formula of P O2.5 is no good to us at all.

What is the percent composition of phosphorus and oxygen in phosphorus-oxygen complex?

The atomic mass of phosphorus (P) is 30.974 u and the atomic mass of oxygen (O) is 15.999 u. Therefore, the total weight of phosphorus in the compound is 61.948, and the total weight of oxygen in the compound is 79.995. The total weight of the compound is 141.943, so phosphorus is 43.6\% of the compound and oxygen is 56.4\%.
