Enter the total mass (grams) and the total number of moles into the Calculator. The calculator will evaluate the Gram Per Mole.
Gram Per Mole Formula
G:M = M / m
Variables:
- G:M is the Gram Per Mole (g/mole)
- M is the total mass (grams)
- m is the total number of moles
To calculate Gram Per Mole, divide the mass in grams by the number of moles of substance.
How to Calculate Gram Per Mole?
The following steps outline how to calculate the Gram Per Mole.
- First, determine the total mass (grams).
- Next, determine the total number of moles.
- Next, gather the formula from above = G:M = M / m.
- Finally, calculate the Gram Per Mole.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
total mass (grams) = 70
total number of moles = 4
FAQs
What is a mole in chemistry?
A mole is a unit of measurement used in chemistry to express amounts of a chemical substance, defined as containing exactly 6.02214076 × 1023 particles, such as atoms, molecules, or ions.
Why is the gram per mole (g/mol) unit important?
The gram per mole (g/mol) unit is important because it allows chemists to work with the macroscopic amount of a substance when they know the number of particles and the type of substance. It helps in converting between the mass of a substance and the number of particles in that substance.
How does temperature affect the calculation of grams per mole?
Generally, the calculation of grams per mole is not directly affected by temperature since it is a measure of mass per number of particles. However, if the substance is a gas, changes in temperature and pressure can affect the volume of the gas and indirectly influence calculations involving molar mass.
Can the grams per mole value change for a substance?
The grams per mole value of a pure substance does not change as it is a fixed ratio based on the atomic or molecular mass of the substance. However, for mixtures or compounds, the grams per mole value can vary depending on the composition of the mixture or the compound.
