Chemical formulas provide information about the atoms in a molecule. Knowing how they work makes it easy to find the formula for each chemical. Sulphurous acid was never observed to be in a liquid solution, but it was found to be a gas. Many people confuse it with sulfuric acid, but it is actually a specific chemical with a different formula. It has the chemical formula H.2IN ORDER TO3.

TL; DR (too long; not read)

The chemical formula of sulphurous acid is H.2IN ORDER TO3and it has a formula mass of 82.

The formula for sulphurous acid

A chemical formula lists the individual elements in each molecule and how many of them make up it. They use the standard symbols for the elements and include an index that indicates the number of atoms of each in the final molecule. For example H2O is water, consisting of one atom of oxygen (O) and two atoms of hydrogen (H).

Sulphurous acid has the formula H.2IN ORDER TO3. This means that it contains two hydrogen atoms (H), one sulfur atom (S) and three oxygen atoms (O). The structure of the molecule has the sulfur atom in the middle with the three oxygen atoms bonded to it, two of which are single and one of which is double. The two hydrogen atoms bind to the simply bound oxygen atoms.

The formula mass of sulphurous acid

The formula mass is a measure of the relative total atomic mass of an entire molecule. Although the components of atoms (protons, neutrons and electrons) each have very specific masses in kg (protons and neutrons in the order of 10)−27 kg and electrons much smaller at close to 10−30 kg), the numbers are so small that chemists use a different method to describe them. Electrons are much lighter than protons and neutrons, so their masses are simply ignored. The mass of a proton or a neutron is set to 1 on the relative atomic mass scale. This means that hydrogen with one proton and one electron has a relative atomic mass of 1.

Find the relative formula mass of a compound by adding the relative atomic masses of the components. Use a periodic table to find the relative atomic mass of an element. Using this and the chemical formula, calculate the total mass of the molecule. For sulphurous acid there are two atoms of hydrogen (relative atomic mass = 1), one of sulfur (relative atomic mass = 32) and three of oxygen (relative atomic mass = 16), so in total:

Formula mass = (2 × 1) + (1 × 32) + (3 × 16) = 82

The formula mass of the sulphurous acid is therefore 82.

It should be noted that the periodic table lists more precise relative atomic masses, but only to take into account different isotopes of the natural elements that sometimes occur. In many situations, you can simply round these numbers to the nearest whole number.
