# Amount of Substance Calculator

Input the value of Mass (g) and Molar mass (g/mol) to find the amount of substance (Mass/Molar Mass) using this amount of substance calculator.

## Amount of Substance Calculator

Amount of substance calculator is a tool designed to determine the quantity of a substance used to produce a product. It does this by taking into account the mass of the substance and its molar mass.

## How to use this Amount of Substance Calculator?

To calculate the amount of substance in a mole follow the below steps:

- Input the value of Mass (g) and molar mass (g/mol).
- Press the calculate button.
- Click the show more button to see the step-by-step solution.
- Click the reset button to calculate another value.

This amount of substance calculator will provide you with the result in the number of moles that a substance has according to the input values i-e Mass and molar mass. Also, this calculator provides the solution with steps.

## What is the amount of substance?

In the field of chemistry, there's a fundamental concept that aids in determining the amount of a substance needed for experiments in labs: the mole. The mole provides a measure of the quantity of a particular substance, expressed in terms of the number of particles present in a sample. This concept is pivotal for understanding the behavior of matter, whether on a microscopic or macroscopic scale.

The mole quantifies the 'amount of substance'. It is defined by Avogadro's number, which is 6.022×10^{23 }particles, representing the number of constituent particles (usually atoms or molecules) that are contained in one mole of any substance.

## Formula:

The mathematical formula of the amount of substance is stated as.

Amount of Substance = Mass (m)/Molar mass (M)

- Amount of Substance = m/M
_{m} - m = mass of the required substance
- M
_{m}= Molar mass of the given substance

## Examples

Here we solved some examples to explain the tool in detail.

**Example 1:**

Evaluate the required amount of substance of sulphuric acid (H_{2}SO_{4}) if its molar mass is approximately 36 and its mass is 72.

Solution:

**Step 1: **

Write the data from the question.

Molar mass = M_{m} = 36, Mass = m = 72, Amount of substance =?

**Step 2:**

Write the formula of the weight of the acid.

Amount of Substance = m/M_{m}

Where, m = mass of the required substance, M_{m} = Molar mass of the given substance

**Step 3:**

Putting all values in the above formula carefully and simplifying.

M_{m} = 36, m = 72,

Amount of Substance = m/M_{m}

_{ }= 72/36

**Amount of Substance = 2 mole**

**Example 2:**

Evaluate the required amount of substance of hydrochloric acid (HCI) if its molar mass is approximately 12 and its mass is 24.

Solution:

**Step 1: **

Write the data from the question.

Molar mass = M_{m} = 12, Mass = m = 24, Amount of substance =?

**Step 2:**

Write the formula of the weight of the acid.

Amount of Substance = m/M_{m}

Where, m = mass of the required substance, M_{m} = Molar mass of the given substance

**Step 3:**

Putting all values in the above formula carefully and simplifying.

M_{m} = 12, m = 24,

Amount of Substance = m/M_{m}

_{ }= 24/12

**Amount of Substance = 2 mole**

**Example 3:**

Evaluate the required amount of substance of hydrochloric acid (HCI) if its molar mass is approximately 34 and its mass is 24.

Solution:

**Step 1: **

Write the data from the question.

Molar mass = M_{m} = 34, Mass = m = 24, Amount of substance =?

**Step 2:**

Write the formula of the weight of the acid.

Amount of Substance = m/M_{m}

Where, m = mass of the required substance, M_{m} = Molar mass of the given substance

**Step 3:**

Putting all values in the above formula carefully and simplifying.

M_{m} = 34, m = 24,

Amount of Substance = m/M_{m}

_{ }= 24/34

**Amount of Substance = 0.7059 mole**
