Question

Relative atomic mass of hydrogen ar how to calculate

Answer 1

Answer:

Way to calculate Relative atomic mass (Ar) for standard atoms. In order to calculate Ar, first of all, is to calculate the 1/12 of carbon-12: 1.993x10-26/12=1.661x10-27 Kg; then, compare this value with any other atom which needs to be calculated and the obtained ratio is relative atomic mass for that atom.

Answer 2

Answer:

The relative atomic mass of hydrogen is, 1.008. And in the explanation, all the steps required to solve have been provided.

Explanation:

As per the given question, we are asked to give the procedure on how to calculate the relative atomic mass of hydrogen, along with all the necessary steps.

The relative atomic mass of hydrogen is 1.008. This value is determined by the International Union of Pure and Applied Chemistry (IUPAC) and is based on the isotopic composition of naturally occurring hydrogen.

The relative atomic mass of an element can be calculated by adding up the masses of all of its isotopes, each multiplied by its corresponding natural abundance (expressed as a decimal). For example, hydrogen has two isotopes: protium (1H) and deuterium (2H). The natural abundance of protium is about 99.985% and the natural abundance of deuterium is about 0.015%. Therefore, the relative atomic mass of hydrogen can be calculated as:

$(1.008 * 0.99985) + (2.014 * 0.00015) = 1.008$

Where 1.008 is the atomic mass of protium and 2.014 is the atomic mass of deuterium.

As we can see, the relative atomic mass of hydrogen is 1.008 which is very close to 1.
