# How to Convert Grams to Moles? And What are its Advantages

## What is a Mole?

How to Convert Grams to Moles; The measuring unit MOLE (mol) is the quantity of pure material containing exactly 12 grams of carbon-12 of the same amount of chemical units (atoms, molecules, etc.); as the atoms are 6.022 X 1023 in 12 grams of C-12.

The mole is hence the title used for the amount of 6.022 x 1023 just as the word “dozen” for the value of 12 is used. If you have a mole of eggs, then you would have 6.022 × 1023 eggs. We use the mole to describe the number of chemical substances since each substance has so many atoms and molecules.

The 12 grams are specifically used as a metric as this represents Carbon 12 isotope’s predicted atomic mass (6 protons and 6 neutrons). This indicates that the carbon’s atomic mass or weight (12 grams) is precisely 1 carbon mole. The atomic masses in the periodic table are equivalent to 1 mol of these substances using carbon as a reference.

The reason the mole is considered essential in stoichiometric calculations is that in most relationships of chemistry we utilize the mole as the unit. Effects are balanced based on the number of moles of each reaction element, solution concentrations are described very often using moles per liter or moles per kg of solvent; and the molecules or atoms of an element have already been described as moles of the product; rather than as individual particle counts.

## What Is Molar Mass?

Molar mass or weight is a physical characteristic that is the mass of a substance divided by its quantity. The molar mass act as the conversion bridge between the grams of material and the moles.

Therefore, you can successfully comprehend the method of converting between moles, grams; and even molecules of a substance after you know how to obtain a molar mass. The number of atoms in the elements in a particular compound must be calculated for the molar mass calculation of a compound. The standard units are usually in g/mol, which is grams per mole. Learn in detail through How to find Molar mass.

## Why Convert Grams to Moles?

When chemicals react, they react in basic moles ratios. While the balances which are present in chemistry labs to measure the substances’ mass offer readings in grams. Balances don’t offer moles readings, which creates contradictions while taking measurements.

The difficulty is that when we calculate the quantities in moles of each chemical; we have to convert the grams since that is the unit we calculate from balances. This is where the problem arises and we require a conversion method; that converts the calculated grams into actual amounts of moles.

## How to Convert Grams to Moles?

The molecular weight or mass of the substance must be found first to estimate the number of moles of the given chemical substance. After that, you have to determine the physical weight of the compound in grams. Lastly, you must divide the physical mass (grams) of the chemical by its molecular weight; or mass when you have both of these numbers. You can also use grams to mole calculator to calculate within seconds.

The above-mentioned procedure is given comprehensively, the step by step method, however, is described below:

1. Molecular Weight Determination

The first step is to assess the molecular weight of the substance (or the molecular mass). There are many atoms of various elements present in a compound; and the total atomic weight of the chemical compound creates molecular weight.

1. Weight in Grams Calculation

Next, you have to find the ‘physical’ weight in grams of the chemical substance. A laboratory balance or analytical balance that weighs the substances in grams is usually used to measure the weight of the sample. This equipment is available for measuring the weight of compounds in most Chemistry laboratories.

1. Mole Formula Calculations

Once the molecular weight or mass and the physical weight in grams of the chemical are calculated; the mole count in the chemical substance may be calculated with a simple formula as given below:

Moles Number = Compound weight (in grams) / compound molecular weight
