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 6.022×10²³ 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 (H₂SO₄) 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
